Mother in law still talks wonders about ex in-law.

So I just hanged up the phone with my mother in law, idk what to make of this as she tends to be nice for the most part and supportive, she brought up my husbands ex fiancé, and it really bothers me that she talks wonders about her to me and says what she loved about her, including she wanted to remain friends with her.

This is not the first time, one day she told my husband while I’m sitting in the table with them, she told him he made a mistake when he and the girl broke up. Like it bothers me so so much, and I told my husband, he did talk to her and told her that she should not be making any comments like that including that day told her he didn’t make a mistake because he is with the right person.

I am currently pregnant with their only grandchild and she is buying allot of stuff as she is excited, but I feel disrespected as she once again brought that person up.

I don’t know her at all, but It think that’s out of hand for her to even mention her when clearly her son has moved on. Thoughts?? No rude comments, and no I’m not jealous cause I don’t know the girl nor does my husband care for that girl, he clearly told his mom he didn’t want to know anything about her. The reason they split was because she cheated.
