I met this girl in one of my classes at a bar one night and she was all over me. We exchanged numbers and when I left the bar, she texted me "sweet dreams

". A couple days later we went out to lunch and had a solid date. I was driving by my house and told her she should come over some time to hang out, to which she was receptive. That same night I texted her to see if the bar was worth coming to and she replied "not really." Keep in mind another night I asked her if she was going to a party that I was going to and she replied with "Yes, come!" So after I texted her about the bar, I texted "Too bad. Let's hang out sometime this weekend?" She replied only with "Yeah." I interpreted that as her definitely having no interest in hanging out, seeing as she would otherwise give at friendly response knowing her personality. So I backed off and only see her around campus now and then (I'm no longer taking the class we had together). We're still friendly and talk every now and then, but I'm thinking about trying with her again. Any suggestions as to how I should proceed?
