My new fiance and I have been together for 3 years now and everything has been fine between me and his mother until now. We spent some time with her and her family for the holiday and decided to head out a day early and she flipped out....ON ME!! Saying I'm being selfish while screaming in my face calling me numerous cuss words and made is explicitly clear that she hates me.
My fiance calmed her down while I waited outside and needless to say, it was best for everyone we left at this point. But oh what to do now? And on top of it, we have engagement dinner reservations next Sunday with her and her 20-something boyfriend, his dad and step-mom and dad, and my parents.
Any advice from on how to ease the tension with his mom?
