I'm over sex

I'm too the point where I want to scream. I'm 14 weeks and don't want sex, and haven't since I found out I was pregnant. Well, according to my husband that means I don't want him. I've been sick as a dog my entire pregnancy, lost 17lbs. It's been a battle to take care of myself and my 18 month old daughter but all he gives a shit about is that he's not getting sex. I'm over it. Since this weekend I've been sick, exhausted, in pain and tired and I tell him I want him but no, he would know if I did. Just because I don't act on it doesnt mean I don't want him. I'm seriously over it, this isn't all about him. And mind you, I've still given him sex at least twice a week so it's not like he isn't getting any.
