My fiance (30) and I (25) have been dating for about 5 years. I met his mom this past summer (she lives in a different country) for the 1st time. I was really nice to her but she hates me (she thinks that I'm trying to steal his money, even though I'm going to be the breadwinner (I'm currently in PA school), and that I'm a horrible person). My fiance and his mom argued a lot over this issue when I was there and our wedding is in a few months. She told us she's not coming because it's too far (we think that the reason she's really not coming is that she does not like me).
Anyways, they had a trip planned in Europe before COVID, which they had to cancel. They want to try to do it again and I can't go because I'd be in school. We would also be married at this point. His mom and he asked me if I minded and I said if there was any way they can go in may (since I'd have off for a week). His mom is very adamant about not changing the dates, even though she is retired and can go anytime and my fiance would also be able to go in May. She also did not give a reason as to why the dates can't be changed (other than she doesn't want to change the original plan they had). Should I tell him that I don't feel comfortable with them going because of the way she behaved with me? He also agrees with me about his mom and they talked about it before, but she still thinks she did nothing wrong, even though both of us told her.
