A few weeks ago we went to my DH's brother's engagement party. It was at PILs house, we didn't have the kids so I was drunk (but not majorly so), pretty much everyone was.
I went to the toilet but pil don't have a lock on the upstairs bathroom. When I was washing my hands BIL came in and put his arms around me from behind, I thought it was a bit weird but he was doing it in a friendly way iyswim. When I tried to shrug him off he put his hands up my dress and down my leggings and started to grope me. I pushed him away and went downstairs but he kept trying to grab at me as I was leaving the bathroom.
The next day he text me saying that it was better off we forgot what happened and there was no point telling our other halfs. The thing is DH is really close with his brother and I don't know what to do because I feel I've left it too long to tell him now.
BIL and his fiancé are getting married abroad and DH keeps saying that we should book flights and tickets soon but I feel so awkward about the situation...I really don't want to spend time on holiday pretending everything is alright.
