Drunk flirting.. what does it mean?

Anonymous
My friends and I went out to a club last night and met up with one of our older guy friends there, who I kind of like/lust after.. He's 27, and we are all 19-21. He is a very flirty drunk, and flirted with each of us 4 girls last night. He was touching, dancing, told me "I like you.. I really like you.." and then after trying to get me to dance on the bar and I refused, he told me how much he respected me for not doing it (um?).

Anyways, he ended up "confessing his love" to one of my friends is what she says.. and he knows and is friends with her boyfriend of 3 years. She kept denying our friend and told him she was happy and in love with her boyfriend, but he was persistent with her for a good 20 minutes. She told me later that the reason she was flirting with him was because she likes the attention, and would never do anything with him.

Back to him.. What's weird is that he shows zero signs that he likes her when we are all sober, but when he's drunk he acts like this? When he's sober he'll flirt with me and give me tons of signs that he likes me, but now I'm not so sure. I think he wants a fling for now (just broke up with a girlfriend a few weeks ago) and was thinking she might give him sex because she was drunk, and he knows I wouldn't do that. So I think he sees me as wife material in a few years, but the problem is he just wants sex for now.

So basically I'm confused on this whole situation.. anyone want to help decipher what he's feeling?

I'm also thinking that he picked her out of all of us to try to get with because she was the drunkest. The rest of us were nearly sober, so not fully responsive to his drunk flirtyness..
