My cousin, who I grew up with and have a sibling relationship with, came through a messy divorce about two years ago. It was a horrible and abusive marriage.
Around the same time, she got back in touch with an old boyfriend from years ago, initially as a casual, rebound thing but they're now a serious couple and about to move in together. I've met him several times, both recently and years ago when they were dating and I've always really liked him. He treats her very well and is just a likeable bloke. She has told me she's very much in love and he feels the same.
All the family are really happy she's with someone nice after such a horrible time.
Last weekend we all met up for a family BBQ at his house, where cousin will be moving to soon. Everyone got quite drunk, especially him, but we were all having fun. Near the end of the evening, I was in the kitchen washing up and he came up behind me and drunkenly wrapped his arms around me and said he's so happy to be part of the family and sort of nuzzled into my neck and kissed/nibbled it a bit.
It felt awful. I couldn't be less interested in him in that way. I am happily married with two young kids and happy for my cousin who says she has found happiness with this man. I stepped away and walked back out to the garden in a daze and he just sat down at the kitchen table.
Now I don't know what to do and if I should say anything. I don't want cousin to end up with a man who makes passes at her family but I also don't want to ruin her happiness over what could have just been a drunken mistake I am certain he doesn't remember.
A part of me also worries the family won't believe me as I am overweight and unattractive and cousin is a slim and very attractive woman.
WWYD?
