I'm going through a heartbreak, helllp? :(?

welll, im 15, & literally just had my son two days ago (he was a month early) so he's staying at the hospital for an extra week so his lungs will develope better. my friend austin came to visit. we've been sorta 'talking' for the past 2 months ever since my bf broke up with me. people always tell me how he likes me & everything. he's very very sweet, (even though he's one of the babydad's good friends) & prettty cute. He also tells me how i am beautiful even though i gained some weight from my pregnancy. he has never tried to pull a move on me, which is good because i know he doesn't like me because ive had before. well, there's a couple bad things. 1)i found out he would never date me because he doesn't wanna get involved with the baby, which i understand, but w/e. 2) He still likes my friend jenny. 3) is always out with girls, driving around while blaring his music, smoking pot, skipping school, getting into fights. idk, but the fact that he likes my friend jenny really7 set me off. he didnt know that i like him, alot. so i need help, what should i do?
