What should I do with my girlfriend?

First off who broke up with who? Either way it sounds like she still has feelings for him and the fact that she's hiding you from him could mean that they are dating again and she's just pulling you around for kicks. And how long have you been dating because the max time to get an abortion is about 12 - 18 weeks and it doesn't seem as if she was at the max so if you guys were dating three months ago Im sorry to tell you but she's been sleeping around.
