I’m in a gay relationship and finally came out to my family this year, they accepted me. I brought my boyfriend home for the first time for the winter holidays. He started drinking heavily with my dad this morning, and now he’s borderline blackout drunk and very touchy… horny, to say the least. It makes me uncomfortable since I’ve never seen him like this, lol. And of course, he’ll probably be hungover on my birthday tomorrow.
He might have felt pressure to keep up with your dad due to just meeting them / wanting to make a good impression, and not realized how drunk he was getting. Doesn’t excuse his actions in the least, but might help contextualize them… given it doesn’t sound like this is something he would normally do.
