ok.. my boifriend.. Cody.. we've been goin out for 2 months.. so its nothin "serious" but its more than just a casual 2 week thing.. right. n we've dated before. i keep having all these mixed feelings about him.. one minute i'll be completely wrapped up in him.. n the next i'll be wanting to get outta the relationship so fast its crazy. not only that.. but this other guy, Tyler. he's more of a makeout buddy than anything else.. so i wanna be single so i can be with him again..
but heres the hard part- Codys messed up. i always get involved with the crazy guys idk why.. Cody's bi.polar & tends to stay pretty depressed.. especially when he doesnt take his medicine. he has a really messed up family & all kinds of problems.. he feels comfortable with me cuz im the only stability in his life right now.. and i love to help people.. so i love when i can make him feel better ya kno..
i'm even in good with his mom. i talk to her all the time online ((she has msn)) she's more like a friend to me than a mom.. she's really kool.. easy to talk to. but she's always tellin me bout how bad codys life is n its kinda awkward.. n it makes me feel so bad cuz here cody is w. all these problems.. then here i am wanting to break up with him.
the main reason i'm afraid to break up with him is cuz he always talks about how if it wasnt for me he'd run away or kill himself or somethin like that. he already "cuts".. he's tried to kill himself before.. n he was in the hostpital for a week or 2 in december cuz he ODed..
idk what i wanna do?

i think u should break it off before he falls deeper for u... or tell him u dont wanna be his gf u wanna be his best friend? so u can help him without being with him? lol i dunno.. thats a tough situation
