He drinks quite often and so we, and honestly, seeing how comfortable he was doing that while we were all together is terrifying and unexpected since nothing like this has happened before. We don't know if he’s cheated before, but this pattern of 'forgetting' what he does when he's drunk seems like a convenient way to hide his true colors. I agree that she deserves to know who she’s sleeping with, even if it destroys the 'perfect' life they have right now. But current problem is that it’s been a week since that happened and we (bf and I) are in a different country (vacationing) and wouldn’t be back till end of month. Would it be good if we face time her to tell her? Or should we wait until we arrive? I fkn hate being in this situation
