Here's my (very lengthy) response!
Stelena: how they saved each other. I mean, COME ON, in the beginning, they DID. Elena was heartbroken over the loss of her parents, and Stefan came and showed her that love and life DID go on. And she saved him, time after time. And their scenes can be romantic, sweet, or heartbreaking. Sure, it's not the most EXCITING couple (for me, personally, but I'm sure that MANY people find their relationship very exciting and I respect and understand that!) but they can be cute and funny. For example, one of my favorite scenes in the entire show: when Elena is staring at Stefan when she's lying in bed, and he asks her why she's staring, and it goes something along the lines of "I think it's romantic" "I think it's creepy". It was so cute :)
Delena: Oh god, time to explain my OTP, which is something I always have the hardest time doing. I can't even EXPLAIN my immense love for DE. Okay, I love them because Elena is the only person to ever, EVER, crack into Damon's heart and soul and wiggle herself in there, EVEN when Damon didn't want her to. Over time, he found her in there and said "hey, how in the hell did THIS happen? When did I become this person? When did I start to CARE?" Elena brings out everything in Damon that is HUMAN, that ALLOWS him and ACCEPTS him for who he used to be, who he really is deep down, not who he PRETENDS to be. She pushes him to be this person he lost when he first met Katherine, and he becomes the person who is WORTHY of love. He's her protector, her most beloved, her one true half and twin flame. They fight, they go back and forth, sometimes they hurt each other with the things they say, and it NEVER works out the way they want it to, but at the end of the day, NO ONE ELSE can release that PASSION in Damon and Elena than they can. And they will always be there. Fighting, yelling, screaming, hugging, understanding, and loving. That, THAT, is what makes me love Damon and Elena so much.
Bamon: how Damon unintentionally DID start caring for her! Perfect example; 2x18, while he was worried about protecting Elena, he DID also care about keeping Bonnie alive. He spent time trying to fake out Klaus to keep Bonnie and everyone else safe, and now they really do trust one another! And Bonnie and Damon keep each other on their toes, they don't really know how far they can push, they test boundaries and sometimes it ends up TERRIBLY, but then sometimes they gain this newfound respect and appreciation for each other. And while they still bug the CRAP out of each other, they challenge each other. Sometimes they challenge each other to be better, sometimes they challenge each other to be worse, and sometimes they just FIGHT, but the CHALLENGE is what makes their journey so immensely intriguing and TRULY entertaining to watch. And while I don't necessarily see them as a couple, I absolutely adore their friendship and mutual respect and appreciation, as well as caring for each other.
Forwood: Oh GOD, how can I explain? The head cheerleader. The football player. Both starting out incredibly misunderstood and spewed a little bit of hatred from fans. They both were UNWILLINGLY turned into these...beasts and they had NO ONE! They had NO ON AT ALL! And they FOUND each other...they found each other when no one else cared enough to look. Their chemistry, their heat, and their undeniable and extremely loving and incredible relationship was enough to make me ship them the FIRST second I saw Caroline pull an emotional and heartbroken Tyler into a small, friendly embrace. Somewhere along the way, it turned into more. So much more. I just love them too much for words, it's so hard to explain!
Catt: Oh gosh, I will ALWAYS care about Catt. Matt, this sweet, puppy-dog, who was still HEAD OVER HEELS for Elena found this drunken, emotional girl, a head cheerleader who's incredibly bitchy and manipulative, but also bubbly and quirky and with many redeeming qualities, and all he does is be a perfect gentleman, scoop her up, take her home, and while many other men would be scared off by the vulnerability of a drunk girl, he stayed the night with her. He kept trying and trying with her, even when she was a vampire (he did not know this yet) and was acting like "a neurotic control freak on crack". But in the end, he DID tell the Sheriff about her and everyone else, putting all of his friends and his GIRLFRIEND in danger. BUT, he DID say to Sheriff Forbes that he wasn't certain that Caroline was gone. You could tell, he saw the Caroline he fell in love with over and over again, but it was just too much. And he couldn't handle it anymore, and he had to end it. But no matter what, my heart will always be a little soft for some Catt scenes. :)
Steferine: It was Stefan's first love, and Katherine's first SINCERE love since she turned. The fact of the matter is, Katherine NEVER compelled Stefan to love him, and Stefan KNOWS that, he just won't admit it to himself! And Stefan is the ONLY person who makes Katherine HUMAN again, and it's beautiful. Their transitions around each other, the way they talk and threaten and joke and almost kill and communicate and tease and undeniably love is indescribable and I can hardly explain my love for these two. She makes him feisty, interesting, fun and SEXY. I just love their scenes together, just LOVE them.
Beremy: WHAT a shock! I was like "Mmmmm, Jeremy be lookin GOOOD!" and apparently Bonnie was thinking the same! Hahahahaha, I DO love this couple. Bonnie's fire is what really perked Jeremy up and helped him become stronger, he became a fighter, all for Bonnie. He FINALLY got over the terribly saddening losses of both Anna and Vicki, and went for this incredibly beautiful and powerful girl who was there all along, and he never even realized. And Bonnie's initial freak out when she realized she wanted to be with him was SOOOOO FREAKING CUTE, like her "oh my god, I saw this kid when he was like, ten years old! I've known him my whole life! I saw his Bieber swoop phase! I just CAN'T feel this way about him!" But he REALLY made Bonnie bearable, he brings her down a few notches when he needs to, but not EVERYTHING is perfect, which is what I love. The way I look at it: Season 3 is going to make them, or break them, once and for all. I'm seriously hoping for it to make them, because they have A LOT of potential!
Staroline: Awww, every time these two have a scene together I have to squeal and restrain myself from saying "Caroline, smooch him!! You smooch him now!!" even though...well you know the circumstances! Stefan became Caroline's protector, he cleaned her up and helped her, teaching her how to restrain herself against the need for blood, he told her and stayed true to his word that he would never stop caring about her and ALWAYS be there for her. He saved her from the werewolves, got her home safely, and arranged for her friends to help her the entire night because he KNEW when NO ONE ELSE noticed that Caroline was NOT okay and she needed someone. Stefan has always been there for her, and I think unintentionally, he let her into his undead heart and she will always have a place there. They're the best of friends, it's Stefan's new Lexie, and not to mention their chemistry is HOTHOTHOTHOTHOT. I mean, put those two together and the SCREEN goes on fire! I basically ship Caroline with every guy (minus Damon...sorry DC-ers!) and Stefan with every GIRL (minus Elena...sorry SE-ers!)
Datherine: HOTHOTHOTHOTHOTHOTHOT; I mean seriously. Plus, Damon spent 145 YEARS looking for this bitch, and his devotion and love for her made him blind and COMPLETELY willing to forgive and forget that even when he knew the truth about what she did. He accepted her for who she was, a vampire, and never feared her, even though he should have. He accepted that he had to share her with Stefan, even though he wanted her all to himself. And even though Katherine doesn't like to admit it, you can tell in 2x21 that Katherine is incredibly saddened when Damon doesn't even want to say goodbye to her. AND, she brought him the cure, when she didn't even have to, and she let it be known that at ONE point, she DID love them both. I think that's really nice. :)
Ummm, how many more am I missing? Guhhhh, I don't want to write MOOOREEEE! I think I'll leave it at that! Hmmm, that was hard to write, considering I don't even like some of the couples I wrote about (it's easy to guess, I think XD sorry, guys!) But SPREAD LOVE, NOT HATE! WOO!
