Hey u guys! How do u deal with ur bfs when they had sex with u and then dump u when u tell them u might be pregnant?

My bf dumped me when I told him that I might be pregnant,without a reason either.It's so not fair when i'm crying and freaking out that I might be pregnant and he's acting like nothing happened.And now he's flirting with other gurlz (we're in the same class)and it really hurts me.He has no idea what i'm going through.Hate him soooo much,so want to kick his ass! I guess i'm kinda in this thing alone.

Do u guys have msn so I can add u and chat?I do need someone I can talk to and u guys rock
please let me know.Thankx sooo much
