Last Friday, my Ex introduced me with an old friend of his. After we drank a lot he became drunk cause it was his first time drinking. He started to hit on me. Well, I know this guy is straight cause he's currently dating with girl. But the second time we were to gather, the same think happened again. After he becomes sober, he barely remembers anything & acts like normal again. I don't know what do with him.
Nothing. He may be straight, or he may be closeted, but either way, "three beer queers" are bad news. Just keep deflecting his advances, and if at all possible, don't hang out with him/them when they're drinking. Lex
Do what Lex suggested. I highly doubt he forgets everything and has critical amneisa. Ask him in a private area, where his friends can't hear. Sound very honest, polite, and neutral and ask if he perhaps is gay and explain what he's been doing. (It might sound like you were trying not to take advantage too, and that could earn brownie points!)
