Family drama

I didn't know how to title this to be honest.
This is gonna be a bit long... Sorry!

So FBIL is getting (possibly) married next month. We are pretty sure he is not going to invite us. We haven't received an invitation and he hasn't spoken to FH in months either. So, it is most likely the case that we won't be invited.

He has been a bit of an ass to us before and he is a problematic part of his family for sure. He has been talking bad behind my back and to my FH and FH has punched him for saying bad things to my FH's face.... He doesn't like me, for some reason, at all. And truth be told I don't like him and I don't care for him BUT he is family. I should mentioned that the first time I met FBIL I was not with FH and he made a few passes at me, even then I found him a bit.... Repulsive. He was even trying to break us up a couple of times..

All of that being said, he is family and obviously FH wants to invite him. Of course I understand and of course I am ok with it. We even spoke about inviting him even if we know he won't show up.

But I wanted to ask, after not being invited to one of your close family members wedding. Would you invite them to yours?
Not saying I won't invite him but I wanted to know if someone has gone through something like this.
