To still think about this years on?

[User6574]

About 10 years ago I slept with somebody, it was a one night stand and I was single.
I'd known the man a good few years and that he had married and had moved away a few years back, but he spent the night telling me how they'd split up etc, I suppose the drink didn't help but I believed him.

Anyway a few weeks after that night he added me on fb and I discovered he was still 'happily' married and then I went on to meet somebody and I tried to put it behind me.

I know he is still with his wife though now and every so often I think about how she has no idea that he lied to sleep with me and no doubt to others. I would never tell her especially not years after it but I do feel guilty when I see pics pop up of them playing happy families (wife tags a mutual friend in pics sometimes, I'm not fb friends with neither of them and I dont personally know the wife)
Anybody else had a situation?

I haven't experienced this but I would block them so you will no longer see their pictures. Life is to short to waste emotional energy thinking about them.

I know what you mean; I slept with a friend casually a few times and only discovered afterwards that he’d started seeing someone fairly seriously during that time. Every time I saw something about them on social media it made me feel guilty and it wouldn’t surprise me of he did that with other people as he tried it on again a while later.
