I hate my fiancees mother
What happened? Why do you hate her?
One of her qualities is that she is a giant baby.
I understand, but you should try and get along with your fiance's parents if you can. Otherwise it could strain your relationship with your fiancee.
Why should I do that? My fiance has no problem with everything and he thinks that his mother is the best of the best. I don't love her mother.
Because you will see more of your fiance's mother moving forward and hating her will make it like a stereotype that married couples hate their in-laws. Try to prove that the stereotype is wrong and maybe put an effort to invite her over and who knows, you might even learn a lot from her about your fiance and in your daily life.
