Last week I met a chick when coming back home from a party and turns out she lives down the hall from my apartment. I escalated and brought her back to my room and fucked her. Afterwards I walked her back to her apartment and the morning after I sent her a text saying I had a good time and she replied that she did as well. Last night (a week later) I texted her asking her to come over to smoke weed but said she was too tired so I just told her no worries. When we had sex I took her virginity and I'm surprised that she seems distant. That night last week she was all over me but it seems like she doesn't really care to see me at all. Do I just wait for her to initiate at this point? I don't want to seem desperate or overbearing. Any advice would be appreciated.
