Background: We dated starting in February and began a relationship in April. I left for 3 months for a seasonal job over the summer and came back mid August. Before the summer, I lived on campus and had my own room. Now, I live at home to save money.

Problem: It began a few nights ago when I asked her to come to a college town with me and visit my friend (we had been before). She declined and everything was fine. Asked her to go the next weekend after she works with another friend of mine (female, but she's met her before and I've clearly communicated its platonic). She declines again but her text is more austere.

From then on, texts have been void of any love, flirting, smileys, etc. Very out of character. I met up with her at my school yesterday. I wasn't all lovey and clearly frustrated (not mad but I was letting her know that this behavior wasn't acceptable with me). I confronted her outside about how she's been acting, she blew it off as nothing (of course) and I continued to probe her. She kept trying to kiss me and hug me. I didn't give up and refused to reciprocate affection. When I had enough of the interrogation I walked to my work on campus with her. We were holding hands but it was more her holding mine (I didn't squeeze or anything and she kept stroking mine with her thumb). Once I got to work I asked her again about her behavior. She dismissed it as being tired and I told her I'm not stupid and I know when something different. Still, nothing. So, I asked her to dinner tomorrow night, gave her a pretty weak kiss on the lips and went to work.

I was furious. She obviously knew but wasn't fighting it, she was trying to make me happier. Didn't work. My question to TRP is this: I planned on confronting her again either tonight or tomorrow night. I'm going to say something along the lines of 'I'm not going to stay in a relationship where we don't talk to each other. I don't need to put up with this high school bullshit.' Should I try and get her to meet up tonight? Or should I wait for tomorrow night? I've already decided if she cancels tomorrow night I'm going to break up with her unless she decides to explain herself and has a good reason.

I don't want to put myself through this. It hurts enough having her be so distant without telling me whats up.

EDIT: I'm 22 and she's 21

EDIT 2: A little more background. I was single for 4 years. In those 4 years I've had sex with a decent amount of chicks and made out/oral sex from even more. I went into this relationship because I was tired of the single life and wanted to try out something more serious. Just so everyone knows I'm not some beta with babby's first relationship.
