I agree. But the only thing i could think of why they would be pissed is because you either a) said something to them in your drunken state that was extremely hurtful and you dont rememebr (but in reality you were just being sarcastic) or b)they hated the way you treated your ex and feel that you might act that way to them at some later time.

I go through this shit too all the time and its just not needed. Thats why, at least recently, i just hang with my guy friends and get wasted. The drama level in my life is way down for once, so im a bit happier. If my girl friends want to see me when im drinking, then they are at risk to anything. And they know that now. So, i say, stop drinking with them, unless they accept what your going to say in your drunken state. Good luck buddy
