What do you do?

What do you do when your boyfriend seems to be so annoyed with every thing you do? I try so hard. All I want is some affection from him! We've been on/off since February 14th 2010.  He says that he loves me but I'm living in a fairy tale world because I want him to show me affection, cuddle, love on me, things like that. I'm going through so much stress right now I just had our twins 15 weeks early they are in the NICU I had to have an emergency c section I'm still recovering from. It's only been 3 weeks. He gets annoyed and mad at me because I don't want to have sex. Yeah, it's been a while I get it. I was in the hospital for a month and a half! I want sex too! But I don't want to bust my stitches! We tried last week and it hurt like a bitch. I don't want to anymore. I'm sick of feeling like crap and being told that I am living in a "fairy tale" because I want to feel loved instead of a sex toy! I love him I really do. He loves me I hope. He makes sure I have everything I need cloths/food/transportation. But I seriously need to know what to do. He won't talk to me. All he literally thinks about is vehicles. He deals with his emotions like that. He has a total of seven now. Only 1 is legal and running.
