I don't know if I'm posting in the right place, or anything so apologies if I've got this wrong, I'm new here.
To cut a very long story as short as possible, myself and and now ex-partner split in February. We've kept an amazing friendship and things have seemed great.
Or they did until the weekend. On a very rare night out we both had a little too much to drink and I spent the night at his as I'd drank too much to drive. We ended up having sex, and now I'm guilt ridden as he has a new girlfriend.
I want to tell her but I know that wouldn't benefit any of us, so I'm here to ask, what would you all recommend?
