Been seeing this girl for over a year, LTR for 3 months now. Everything has been fine. Shes really submissive, does anything I ask of her, cooks me breakfast, I fuck her good, I've been holding frame really well, only really text for logistics etc all good stuff.

She's a uni student. She hasn't been out in town since we've been together. Last night she went out with the ski club for their elections social (messiest night of the year). Would have gone myself but didn't want to take a day off work for it. A bit of backstory, my best mate from college is the president of the ski club and I know everyone in it. It's how I met her in the first place. I have no problems with her going out with those lot.

What I do have a problem with is how drunk she got last night. I received 10-15 WhatsApps from her throughout the night of her just being a drunken mess. (I ignored all of them as I was busy) Got a snapchat from her flatmate of her passed out on their sofa and one from her after that so drunk she couldn't look at the camera properly.

Before we got together I had mentioned that I don't think girls in ltrs should be going out getting smashed in town. She agreed. But that's all we've ever talked about this boundary.

She text me this morning saying she's really sorry about last night and a few minutes later "are you annoyed with me?"

Im going to respond with "if you want to get that drunk in town, we aint a good fit"

I don't want to mate guard or look controlling but at the same time want to make it clear I won't accept this from my gf. Any advice?
