I'd been on a dry spell for almost 2 years until a few weeks ago. This girl in one of my classes recently became single. There had always been chemistry between us. A few days go by and we end up fucking. After this, we have fall break and she goes to Vegas. When we see each other again, she seems much more reserved and not nearly as sexually interested. She prevents me from going any further than making out.

I've asked her to hang out a few times each followed by an excuse. My gut knows something is off, but I keep saying, "Maybe tomorrow she'll...". It seems like I'm being strung along. I see this girl five times a week. How can I control my feelings toward her? I understand it's because she's my only point of sexual contact that I'm becoming attached. Do I cut off all contact? I find myself reading way too deeply into every interaction/thought I have about her. I can rationally tell myself to have outcome independence, but emotionally it is much harder. Any advice is appreciated.
