I guess i'll kiss my freesom goodbye

So my boyfriend and I have a pretty good relationship, pretty open. Open, meaning able to talk about things or share things that maybe some couples may not be able to talk about or maybe starts an argument. We both go out with friends or without each other from time to time ( me more than him). Generally these outings involve alcohol. So the past couple of times I've been out without him, I seem to end up in the dog house or sick as a dog. Which I do find a bit strange because either way they are both done unintentionally, I think I can usually use some restraint or have moderate judgment. Last week I went out after school, by myself just to get out for a bit, some "me" time.  I said I was just gonna have "one drink" . Well, let me tell you! One turned into two, which turned into three, which turned into friends arriving, which turned into SHOTS , which turned into no communication on my part. I can completely understand my boyfriends anger and frustration, he wanted me home and I was out, late, doing God knows what in his mind.  I was sick for two whole days on top of the " I told you so " or " you deserve it" treatment. Basically I can never go out by myself ever again! The completely crappy part is it's 100% my fault. We had something good and I guess I completely took advantage and abused it.
