Am I in the wrong?

I went to my OB today and he put me on bed rest because I'm dilated at 33 weeks. Well I told my boyfriend that and he calls his mom and she suggests we go stay there for a couple of weeks in case I need help. (This woman has also said I'm the biggest mistake of his life and plenty plenty more things.) he suggested we get rid of the cat and I just got very emotional. I don't want to stay there with her whether she is helping with money or not.. I especially don't want to just leave my car here by himself for who knows how long (of coarse he will be fed daily) I live about 15 minutes from the hospital so my boyfriend thinks that this is a good idea. I just want to stay home and get my home ready for my girl. I don't do well with change and living with her.. I already miss my home... I don't know what to do because he keeps saying I'm selfish and not thinking of my baby.. what do I do?..
