Boyfriend vs. Mom

Okay, so last week my mom met my boyfriend for the first time, and she didn't say anything negative about him... until now.  She picked me up from his place and stated that it's done with me and him.  Obviously very confused, I asked why.  She told me she just didn't like his vibes when he came over basically - (and she assumes that he makes fun of her with me, which is false).  Also, she went on to say that if I have to get a job because if I get pregnant, she will not pay for the abortion.  I don't know how to handle this situation.  I understand her protectiveness for me, but he has not been out-right rude (or at all); otherwise, I would have already broke it off.  Help?
