Am I being over dramatic about this?

My fiancé and I got on to the topic about his family. They are beyond toxic and kinda expect him to give them everything they wish.

That’s on him I just said my opinion and left it at that.

Well I ended up having a miscarriage last year. She accused me of lying to him about the miscarriage but he was obviously there during that time.

Now all of a sudden he’s telling me I need to get over the fact that she said I was lying about the whole thing.

I just can’t get over that I can never respect anyone like that.
