I'm using being pregnant as an excuse
An excuse for what?
I don't feel like doing the housework, so I will get my husband to do it since I'm pregnant.
Pregnancy does not end your obligations and using it as an excuse to get your husband to do your work for you is dishonest. Take on what you agreed to do and don't make excuses.
Fuming, my husband fucking sucks.
You should just do what you can. I know being pregnant makes you tired, but as long as you try and get stuff done, you husband can pick up some of the slack.
