Husband and mother in law rant

I'm not really angry, but The other night I found out my husband and MIL  have been talking about me. Saying I'm not pulling my weight and that I'm lazy.... I'm 30 weeks fucking pregnant. I STILL work. I go to work five days a week. I don't hold my money from my husband. I also do all the cooking and cleaning at the house. It just really hurts my feelings they think this way about me. I try so hard to keep up and yes my husband makes more money than me but I can't help that... And unlike him I don't want my family and friends to have a certain opinion about him so I can't vent to anyone else but on here. 😞 I feel so alone.
