Long story short:

Me and my best friend went out of town in 2019. He cheated while we were away and eventually his stupidity led him to get caught by his girlfriend. They broke up and took him a year to get her back--lost frame. I didn't do anything wrong but the girlfriend thinks it was entirely my fault because I was an enabler.

While our social group is connected, it seems she is flipping the script to make everyone against me. Now whenever there are gatherings it just isn't doing me any justice.

Best friend lost all frame and now he's just under her spell. We don't talk anymore. Seems like I've been outcasted in the group as well.

Any advice?
