My future brother in- law has been nothing but rude to me for the pass 6 months. I’ll be talking to someone at work and he’ll walk by hear half the conversation and a week later he’ll go to my fiancé and say he heard a “rumor” about me but yet one one else would hear it. This happened like 3-4 times. I’ve gotten to the point I don’t wanna talk or even talk to him. I’ll go to work do what I have to do. Talk if someone has a question then go home. My brother in-law told my fiancé that I’m acting childish Bc I won’t talk to him. He said a whole lot of other stuff about me. I told my fiancé he’s not invited to the wedding. Do you think I’m wrong? Am I acting childish?
