Soo in high school I had a tight group of friends, all of them are for sure invited to the wedding (we are only 24, so high school wasn't super long ago and most of us remain fairly close) except one, he's a maybe.
one friend got married at about 20, not long after I had broken up with a bf of 3 years. essentially, a groomsman (who was recently out of a relationship also) and I ended up drinking and talking together all night and slept together. we talked about it briefly the next day and a few days later and nothing ever came of it. we're still friends (not super close), but it's not weird. here's the thing though, I have never told fh that this guy and I slept together, just like he hasn't named off every girl he's slept with. so what should I do. not invite him? invite him and still not tell fh? I would like for him to be there since everyone else from the group will be and when I went and saw the married couple last weekend, said groomsmen was over and we talked about the wedding
