Thanks everyone for all your advice and responses!
So, we get to my formal last night, and he shows up! FYI, our formal is not in the town of where we go to college, so him and his friend "happen" to be in the same town we are last night, so they just decide to "drop by" for a little bit. Well...four hours later they decided to leave.
It made me completely uncomfortable since I had a wonderful date and I decided to have the time of my life last night and not worry about him. He came up to me and talked for a few minutes, but then my lil sis grabbed my hand and pulled me on the dance floor. We probably spoke all of five minutes total, and then he just sat there with his friend and a couple of my sorority sisters and just watched me dance.
I've just decided that I'm not going to worry about him. There are way too many other guys here on campus and if it's meant to work out, then I know it will. Like one of you said earlier, he should be the one to make the initiative and call me if he wants to talk. I feel like I am a very confident person and since I do have a lot of stuff going on, I don't have the time or energy to put up with his wishy-washy drama!
