My husband thinks I am cheating on him?

My husband has changed recently. For some reason, he has started doubting everything I do. He is convinced I’m cheating on him. Even when I go out with my girlfriends, he calls me and asks if there are men there, insisting that he knows there are men and that I’m with them. He follows me places, stalks me, and keeps telling me that I will cheat or that I’m already cheating.

It’s crazy because I’m his wife and the mother of our 3-month-old daughter. I go to work, take care of our baby, and take care of him. I’ve never cheated, nor am I planning to, but for some reason he is absolutely convinced that I will or that I already am.

I don’t know what to do about this situation. I’m trying to think of my daughter first, but I don’t understand why he always doubts me when I’ve never done anything. And when he gets jealous, I get scared for my safety. I constantly reassure him and try to calm him down because I’m afraid of what might happen if I don’t.

I used chatgpt to edit because English is not my first language.
