<human>: Reddit my best friend has started to become very condescending since she moved out last Monday (first time out of home). I understand that it's all very exciting but she's started to talk down to me as if she's more important or more of an adult now that she's moved out. I've let it slide because I wanted her to enjoy her new home but at her housewarming I asked if I could bring the guy I was seeing she straight up said no plus ones. I get that too, but c'mon I'm her best friend? Not to mention two of our friends couldn't make it so he could have taken their places but Nup. Now since that night she's been really cold towards me and is saying 'we need to talk'. I completely agree because I need to talk to her about her attitude but for her half, for lack of a better term it sounds like she's breaking up with me. 

But I have now talked to one of my friends who say she will be on loudspeaker when we talk and assures me that my mate is not pissed off at me just worried. Now I think I know what is going to happen. She seems to think that when we do go out drinking (which is twice a week, which I think is fairly normal for 20 year olds) that I drink too much for A. My stature and B.  being a girl. By the end of the night she snatches the drinks off me which just pisses me off because regardless of her opinion, it's rude. She never says I think you've had enough she just gives me dirty as fuck looks and snatches.

Now this seems like an intervention but I don't think it's necessary. I know she's going to pull the card 'me or drinking when we go out' which isn't fair. I'm scared shitless because I hate confrontation. 

Reddit can you please give me advice on what to do/say at this talk? Im worried that I'll snap at her and ruin our friendship because I'm annoyed. 

This is in a couple of hours too. Please help!
