Went on a night out on Saturday and got quite drunk. Bumped into a guy that a friend of mine had been on about 3 (maybe 4) dates with, when I asked her about him about a month ago she said she wasn't going to see him again because there hadn't been a spark.
We ended up kissing, that was it.
I text my friend the next day to tell her what happened and she was completely fine with it and even said I should go on a date with him etc.
Met up with her today and she admitted that the friend I'd been out with had text her on the night and told her about what happened.
Aibu to be a little upset by this? I think said friend should have said to me I think you should tell her what happened or I will etc. Because I was always going to tell her.
(Just a little disclaimer I would never have kissed him if he was still dating my friend or if she was still interested in him)
