My older brother and I used to be really close. Then a few years ago, I started dating my fiance who was also my brother's best friend which at first he wasn't a huge fan of but he got over it. Everything was going well until my fiance and I mutually decided to take a break. We had just graduated college and neither of us knew what we wanted. During that time, my fiance got really hammered one night and hooked up with someone else. About two months later, we got back together. He was completely honest about what happened. While it definitely sucked to hear, we weren't together during that time. My brother views it as cheating though because my fiance and I were still talking and occasionally hanging out purely as friends during that time My brother has completely cut all communication with my fiance and I. We have however been around him a hand full of times at family functions. He doesn't talk to either one of us and pretends like we don't exist. My entire family of course knows the situation, but we don't really talk about it. I decided to invite him to our wedding hoping just maybe he would consider attending. He hasn't RSVP'd so I stopped by his house after dinner just to see if I could talk to him. He didn't answer the door even though lights were on and his car was parked in the driveway. About an hour later, he texted our mom that he doesn't need to reply or talk to me because he doesn't own me anything. I am so devastated. I've been ugly crying and everything. I can't imagine my wedding day without my brother there. I wish I could change how he feels, but I know I can't. My parents have been really good at not taking sides, but I know it hurts our entire family that we are divided. I guess I just really need to vent. Any words of wisdom?
