I dated this guy for 6 months about 2 years ago (he dumped me), and we reconnected a few months ago. We talked over FB and then we got coffee. We talked for over 6 hours, and he kept trying to prolong the conversation even after I told him I was seeing a guy at the time (I'm not seeing him anymore). There were a few other flirty moments on his part, but I didn't feel comfortable responding to them. He disappeared altogether after hung out, and a couple weeks later photos of him with his new girlfriend materialized on Facebook. Apparently he asked her out a week after we met up, and they got really serious quite quickly. I still see him around campus and he often stares at me/tries to make eye contact with me. Did I miss my chance with him, or was he just looking for a "fun time" while he waited for another girl?
