Baby mama drama, pleeeeeease help?

I'll try to make it short. A couple of years ago, I was reconnected with an old high school flame. We dated for about a week and things were going beautifully between us. One day he told me he was in a relationship but he was going to break it off. Later that day she called my phone from his phone crying about him breaking up with her. then she called me from her phone. The next day he told me they were going to work it out. Fast forward 2 years later, they now have a infant (8 mnths) and they are broken up for good.He told me that the reason he stayed with her is bcuz she said she was pregnant (then had an abortion). She claimed she was moving back to her home town, but 2 wks later she was back. She knows me and him are dating and is causing more drama than ever, emailing me, she even came to my house and tried to fight me. I hate drama, but I have responded to her emails. She is very manipulative and I think she is crazy, what can I do to stop this?

Also he has told her nto to contact me. And she is doing things like asking him to come over bcuz she cant stop the baby from crying, or, the baby fell down

This is sooo typical of "baby mamas". They will almost do anything to keep the man that fathered their child in their life. I mean it is understandable, you find someone, fall in love, have kids, and live happily ever after right?? Not!! This def. is not always the case. I was in somewhat of a similar situation. Although, she was not going to this extent. Mainly due to the fact that they were never in a relationship. She got pregnant after a few sexual encounters and then that was it. Hence, the drama! They feel they have some sort of hold over the father of their child which is completely untrue. Only sometimes, there are men that don't put their foot down and set boundaries. If he really wants to be with you then he will put her in her place. Trust me, the little things do count because she will eventually see. Mine took a little less than a year to see that she never stood a chance and never will. I think it is hard for them to let go of that especially if he is in a serious relationship then, they start to feel as if they may loose him for good. In all reality, either she messed up her chances and in my case, never really had a chance other than them laying down together. I myself, couldn't understand this whole thing. I thought she was a psychopath and she somewhat is. I just try my best to be the bigger person and keep the child in mind always. She will fall back once she sees how strong you and your relationship is. Baby mamas are the worst!!!!

I think I would tell your "boyfriend" you want to cool it for awhile, give him a chance to really end the relationship, set up rules and boundaries for his ex. This is not a very good situation for you to be involved in.

I would dump him frankly.

Woooow. thats crazy!! I know how you feel though, almost. My boyfriend divorced his ex becuase she cheated on him. and then she said she was pregnant. no one knows who the father is, she says its him but who knows. Anyways. she found out we are dating and started doing the same thing to me that your bf's ex is doing to you. shes like 6 months along now and theyve been divorced 5 months. All that i can say is do not contact her. do not give her any sort of reaction because that is what she wants. Stay away from her completely and let her get over herself.

OH NO NO NO NO NO Jazzy doesn't put up with that mess! Baby Mama Drama is not my thing if he said it was over it must be over if it keep going file a police report and dnt try to handle it your self it might go way to far you might not take my advice but these are the stern words frm:

I was in a very similiar situation. She's crazy with you but I bet she's nice as can be to him, right? I have to agree and say get out while you can. There is a reason that she feels comfortable enough to continually harass you. There is a reason why she feels like she can call him for every little thing. He needs to handle this situation and you need to get away until he has it handled. It is very hard to do, and I'm sure you do not think that leaving is the answer. But believe me, it is. There is much more going on here than you think. He did not just stay with her because she was pregnant. No one forced him to keep screwing her until she got pregnant again. This guy is very confused. GET AWAY!!!!
