I don't know what to do!

So my best friend (he's a male) has invited me to his wedding. But his fiance hates my guts. She feels that all this time I've tried to take him away from her. I've never tried that. I was dating someone when she was accusing me of that! Anyways. I've known him forever it seems (longer then her!) I've known him for 9 years. Again he is my best friend! We've always had each other's back.

I've even tried to take steps back so she wouldn't be bothered but every little thing bothers her!

For example. For the past 5 years he and I have snowboarded. It's our thing. Sometimes there are other people but most of the time it's just us. She got so mad when she heard about it that I apologized and didn't board with him all season. I kept making excuses.

What do i do! I will respect her but he is my best friend of 9 years!!! I feel bad for him too because she told him he has to uninvite me and he refuses so it's causing issues. Should I just not go to my best friends wedding?
