I've heard of a lot of people cheating on their SO and feeling instant regret, then trying to scramble and save the relationship but does no one realise the gravity of their actions DURING the deed?

My bf and I had a drunk threesome with one of my best friends not too long ago, the thing is that she has a gf. She has expressed her feelings about the relationships she has with her gf and that it's not that great but absolutely not terrible either. She did not feel any regret towards her gf for cheating on her and the threesome wasn't the first time she cheated either. At this point I'm worrying more about her hurjting her gf than she does. This kinda haunts me, even when I was drunk I couldn't stop feeling bad for her gf. I don't know how to even feel towards this friend anymore...

I don't think that this comment would add a lot to the discussion since there are too many questions still unanswered but I just needed a place to vent :/
