so a year and a half ago my boyfriend-before we dated- was seeing this girl. we are both 22, he was 21 at the time and seeing this 18 year old girl. complete whore. I think he was teh 18th guy shes slept with. and toward the end of thier 3 month fling, she wanted him to have sex without a condom and she wanted him to go inside her and she kept talking about kids. Obvious she wanted a baby. well they broke things off because he was creeped out about this, and she proceeded to have sex with like 4 other guys within this time frame, and became pregnant. she said it was one man's kid. then when he decided he didn't want to date her anymore, he got a paternity test. not his. now my bf of almost a year might have a child. neither of us want this. its a burden, we want to start a life together and have our own family one day. and I just don't know how to cope with this...its not for sure, but its very difficult to stomach the man I love having a child by another woman. call me selfish or old fashioned. but i don't want a "just add water" family. I mean a child is bad enough, but having to deal with his crazy ex for the rest of my life if I am with him, is almost worse. I just I am selfish and can't stomach the thought of another woman having the man that I love's baby. And don't be mean, we understand its not the kids fault for being born. But its like she is so young, and the kid will be brought up in a non traditional enviroment, it would have been better to put the kid up for adoption to give em a good life with loving parents. Can somebody please give me some advice 
I dont know what to do.
