Me and BF broke up for about a month, it was a bad time for both of us. During this time I genuinely didn't think we'd get back together and went out one night and got off (extensively) with someone in a club classy I know. We also texted a bit after.
We're now back together and everything is peachy but I don't know whether to tell him what happened? I've obviously stopped talking to the guy and I don't feel guilty about it because we weren't together but we live in a small town and he might hear it off someone else. After some investigation facebook stalking the guy I kissed has mutual friends with BF. So should I tell him?
No. You weren't together at the time, and nothing came of it anyway. If this guy or anyone else is tactless enough to say something, deal with it then, but you have nothing to apologise for or explain IMO.
Thanks Dreaming, that's what I was thinking but then I feel bad at the thought of him hearing from someone else and think I should maybe tell him! I tend to overthink things so think I'm getting worked up over nothing.
It'll just open a can of worms that you can do without; you aren't (and definitely weren't at that time) beholden to him. It's a very misguided idea to "unburden" yourself, it really is none of his business and nor should it be
