I never did. Thank you for letting me know. I feel bad about a lot of things now… I have tried asking mechila from guys I went out with, but it’s a bit awkward. I’ve never been sure if it’s the right thing to do or not. It’s kind of like asking someone mechila for speaking L”H about them (which Rav Yisrael Salanter, zatsal, says not to do). I always did it through other people so it was less awkward, but still…
I don’t know if I could have done things differently than I did at the time. The situations I was in probably would have made it impossible. But I still feel bad about possibly having been the source of someone’s being hurt, even if I couldn’t help it. “Megalgilin chova al yedei chayiv”.
In any case, I very much appreciate your letting me (and whoever else is reading this) know.
