Should I go to her wedding? (Trigger warning- SA)

One of my friends is getting married next year, Ive known her for over 20 years. I want to go and see her marry the only guy I have ever approved of lol. But I have an issue with a member of her family.

She had her high school graduation party at her uncle and aunts house because it was big enough to accommodate her large family. After everyone but her, her brothers, a few friends and I had left we started drinking. Yes it was stupid but her uncle offered and we had 2 older adults supervising (18 y/o logic). Well we all played a drinking game where if you picked a certain card or something (I don't remember) you picked a person to take a shot. Well her uncle 90% of the time picked me to drink. I didn't think anything of it at the time and apparently no one else did either. I ended up pretty drunk and everyone else was either drunk or buzzed. We all decided to be safe and just stay the night. I took the upstairs couch laid down and started to fall asleep. That's when I feel someone get on the couch behind me (I was laying on my stomach). I'm not going to get into details but her uncle sexually assaulted me while holding me down and covering mouth. I'm sure it would have went farther if my friends younger brother wouldn't have come up for water (he was 15 at the time). The uncle jumped up and said he was getting me a blanket before walking back to his room where his wife was sleeping. Her brother said I could sleep on the basement couch since it was empty (I'm sure he suspected something). I agreed almost in tears. Her brother took a spare room that was directly in front of the basement stairs and left the door wide open with the light on. The next morning when I was okay to drive my friend was having breakfast with her uncle. I couldn't face him so I told her I wasn't feeling well and left in a hurry. A few weeks later I told my friend about it and she just thinks I imagined it because I was the drunkest out of everyone. Her brother believes me though.

I don't feel comfortable going since I know the uncle going to be there (it's been 10 years since the incident but it still bothers me). He has since divorced from his wife for having an affair with an 18y/o on his softball team. Am I being ridiculous? Should I go?

Edit: my husband would be going with me but I don't want to have an anxiety attack if I do see her uncle.
