31 weeks and feeling so unattractive to my husband.

My husband wont touch me thinks my breast are digusting says they look weird and always ask when will I go back to normal. Then I wake up at night a lot and he talks in his sleep but lately he been saying Jen come closer and then says Jen im about to cum . I don't know how I should react because first of all Jen is his ex girlfriend name and ever since I became pregnant he acts like I'm so ugly and fat and all he talks about is my diet after my son is here . I been feeling very sad last few weeks I keep thinking I'm just emotional . Can someone give me some advice .
