Seen a girl on facebook, totally my type, met her through my bench mate (surprisingly) also on facebook, where I manage to get her in a private conversation. Found out that we have a ridiculous amount of things in common.

My friend wanted to help (I told him I like her afterwards) and invites all of us to a pub. On private, as we both like rock music, we joke about going to a rock café where he wouldn't come. She says "he won't like that", I say "It's his problem", she says "yeah. If he doesn't come we go alone". So I could say she's already up to meeting me. We kept talking and things went fine, spiked her well despite my normally weak textgame. Did the mistake of not asking her out though...

After two days, I text her again. I sent a link from an application to a workshop that I have to promote, in which she showed interest two days before. She said she'll think about it, and was really cold to me. I decided that she's not in the mood and I let her alone.

Now I believe that she liked my classmate and she used me to get closer to him. He's much more of a pimp than I am, in some ways. And that's why she was cold to me the other night: my friend showed total disinterest in her between our conversations and they stopped talking completely.

If she liked my friend, that's not a problem, he's totally disinterested. I fear that she might not come to that workshop. If I get her f2f, I'll know exactly what to do. If she refuses to go, I can imagine she won't like to come with me on a date either. I think about subtly telling her that my friend comes too (he will) just to ger her there, where I have my eyes, my facial expression, my voice, my attitude, and a setup :). And my friend's new girlfriend.

Should I try that? Is my theory legit in any way? I know I'm overthinking it, but it really intrigues me right now. What other options do I have?

tl;dr: met girl through a friend on fb, things went fine, then she suddenly gets cold after two days. I believe she liked that friend of mine and used me tl get closer, and I think about getting her to an event by mentioning that my friend comes there too, so I meet her in person where I can deal with her. Should I do that? Am I paranoiac?
