So I met this girl on Match.com, very cute like her a lot. We went on one date... it went really well, she asked me if we could do it again sometime and I said yes. So we went on a second date last Friday. We went bar hopping, had a lot of fun, went back to my place... had sex, she said it was amazing. The next morning we're cuddling and she's just going on and on about how much fun she had and so forth. So here I am thinking everything is going good... but I can't shake this feeling that she's bullshitting me. I mean, I'm moderately attractive but I've never been able to pull a girl like this with such ease. And another thing bothers me, she never picks up the phone. When I call she'll never pick up and either call me back hours later or text me the next day. And when she does call back we don't talk for very long. So that Sunday after our second date I call her and tell her that i want to see her again this week. She says that she might be able to do it Wednesday, so I say "OK, call me when you've figured out if you're free or not." Well it's Wednesday and she hasn't called. I called her last night, texted her this morning... but I'm starting to get really paranoid about it. I was fine and happy before I met her, now I'm super depressed and can't stop thinking about her. How the hell do I calm my heart down and not screw this up?
