Kind of a strange question, but let me try to explain. I honestly don't know where this comes from, but everytime I see or hear about my girlfriend drinking I have this serious negative reaction where I get really angry/upset, my heartrate goes way up, and my stomach turns in knots. It's f'ing weird, and it causes strain in our relationship and in my life in general, and I'd love to be able to change it. Last night was the night her mother wanted to take her out to celebrate graduating from college. I wasn't invited along because my gf knew how I react when I see her drink, and she didn't want me to ruin the night I guess. That, in itself, made me feel like crap. Anyway, she went and had a bunch of drinks, and came home a few hours later than she said she would. She never called or anything to let me know she was going to be later, but again, I know it's because she thought I would get upset that she was drinking more than she said she would (she said she would have 1-2 at max). When she came home I started a big fight, and although it's resolved now I still feel like crap over the whole thing. I mean, she was in a safe environment...her mother loves me, and would never let a guy come take her away or something. I'm just not sure why I respond to that particular situation like I do. I can watch friends drink themselves unconscious, and while I find it annoying at a certain point, I never have this type of mental/emotional/physical response. As I'm sure you can guess, I don't drink at all...not because I'm necessarily against drinking, just because I never feel like doing it. The strange thing is that it'll happen if she's sitting right next to me drinking something or if she's with someone else and I'm not there. It's the same response, either way. It also doesn't matter how many...it happens with the first drink all the way through the last. And she doesn't drink often - she admitted last night that this was the most she had to drink, ever. The last time she drank was New Year's Eve, so it's not like it's happening all the time. I just want to change how I react to the situation. I know in my head that I shouldn't react this way...that it's not a big deal, everyone does it, she was in a safe place, she'd never cheat on me, etc. It's just this automatic physical/emotional response that I can't seem to break. Any suggestions on how to deal with this situation?
