What Does It Mean When A Boy Says " I Don't Care " ???

Boys Are So Complicated ! So Anyway , I Had Gotten Jealous Because My Boyfriend Currently Is In A Different State , Visiting Family . Well He Hangs Out With His Two Older Brothers & Both Of Them Have Girlfriends & One Of The Girls Brought Her BestFriend , So When Him & I Are Texting He's Telling Me How This Girl Keeps Flirting With Him & How She's Ugly & How I'm Way Beautiful Then She'll Ever Be . Basically Just Saying What I Wanna Hear .. Well I'm Like Ok . Blah Blah Blah . Then He Doesn't Reply ... Like Oh My God ? So About An Hour Later He Texts Me Saying " Oh My Phone Was Dead & I'm So Sorry . " & Just Being Apologetic . So I Told Him It Was Alright When Obviously I Was Pissed Off . So I Just Replied With One Worded Text You Know ? Until He Finally Figured Out " Hey You Know She's Fucking Pissed At You Because Of That Girl . " So He Asked " Are You Okay ? " & Of Course I Lie & Say " Naaah , I'm Fine ." He Had Said I Seemed Mad . So He's Gonna Let Me Cool Off . 20 Minutes Later He Texts Me A Long Ass Paragraph Of How He Was Sorry & He Doesn't Care About That Dumb Ass Girl . I'm Quoting His Words Not Mine cx So Anyways He Said He Was Going Through All Of My Stuff . Instagram & Snapchat & Facebook . & That He Had Seen A Boy & He Went Through All His Pictures & Saw That He Put A Tbh On My Picture Saying That I was Really Beautiful & Funny & Everything . & Said He Didn't Like That Boy , Buuuut !! That He Didn't Care That I Talk To Him .
