Is this a reason to be so upset? ?

My fiance got out of work at 3:45 and went to the bar then was on facebook mobile while he was there. He texted me at 4:30 asking what I wanted to do about dinner. Im 9 months pregnant and work from home 55 hours a week. I get done at 5:30. I told my fiance I wasnt feeling good and had the blues. He said he would come home and make chicken and veggies and take extra good care of me ext. He came home at 7 and I was laying in bed. He asked if I wanted a hot dog or cheezeburger. I said no Im not hungry and tired ext. I was starving but it was late. He smelled like booze and I know he would fall asleep after he pigged out anyway. He made himself dinner, watched tv then came into bed and read. He tried to talk to me but I was annoyed and went and layed on the couch. 9pm and he is in bed snoring so loud I couldnt go back and fall asleep. Am I being wrong by being annoyed by him? He is so self indulgent!
