For those who are confused with the whole couple thing on Adventure time, here is how it goes:
FINN: Finn had a crush on Bonnibel (PB). But Bonnie didn't love him back. Because of that, Jake looked for a princess that was Finn's age, and found Flame Princess. Eventually Flame Princess became Finn's girlfriend.
JAKE: As most people know, his girlfriend is Lady Rainicorn. It was shown in "Lady And Peebles" that Lady is pregnant. It is unknown if Jake and Lady had the "intercourse"
BONNIBEL: She and Mr. Cream Puff have dated before as mentioned in "Slumber Party Panic".
MARCELINE: Ash is Marceline's ex-boyfriend. Ash sold Hambo, Marceline's beloved childhood toy which caused her to be enraged and dump him.
LSP: She has an ex-boyfriend named Brad, which is being dated by her friend Melissa.

1) In Princess Cookie, she visited the Candy Orphanage. Baby Snaps was still a kid there, and Bubblegum looked 18. It was the past. While Cookie has grown physically, PB still remains the same.
2) In the promo art for Burning Low, Flame Princess seems to very young, like 5 years old. While Peebles in next to the lantern, looking 18 years old.
3) In The Suitor, the oldest suitor said he had been waiting for PB for 300 years. Indicating that she has lived for 300+ years. I think that it is because of Candy Biomass that makes her live.
