Tired of trying..

My fiancé (whom I'm expecting our first child with) is being such an ass lately. He got upset at me because I wasn't in the mood for sex. He literally stormed out of the house, & sat down outside. He then stands up, looks at me & says "I'm a man. I have needs. Fulfill them." as if I don't do anything for him. It's ONLY BEEN A WEEK since we last had sex. Besides, I'm 5 months along & feeling like a pig. Sex is the last thing that's on my mind. When he said that to me, it made me feel so worthless.. I always try to please him & make him happy. He doesn't understand the changes my body is going through & how sometimes I'm just focused on other things. I honesty feel like it's putting a strain on our relationship. I don't know if I'm overreacting about this, or if it's just my hormones. I just needed to vent. Sorry for the long post.😞😞
