So last Saturday night I (28M) went out with a friend of mine to a bar. He saw a girl he knew, so we started to chatting to her and a friend of hers turned up. We will call her Hannah (26F). We are both tall (I'm 6'5, she's 5'10) so had a fair bit to talk about and I could tell she liked me from the outset. Eventually her friend even told me that she liked me. The night then went to her friends apartment, and while Hannah and I are on the balcony smoking a cigarette I told her I liked her and we kissed. She asked me for a lift home so I knew she was up for sex. We got back to hers, and immediately we started kissing and we were fucking all night from like 1am to 6am on and off. Between rounds we were talking and kissing and we seemed to really get along well with each other. We slept for 2 hours, woke up and had sex once more. The sex was great, she even complimented my skills and said I had a big cock etc, and kept telling me how sexy I was. I had shit to do so I left at like 10am and gave her a lift to the shop. At some point I got her number during the night so on the Sunday evening I sent a pretty nonchalant "recovered yet?" text, and she responded to say she had. We arranged to meet up again on Friday, but she said she may have to babysit for her sister so not a definite. Thursday rolled around and she text me "still up for tomorrow?" so I assumed we were game on. Anyway Friday evening rolls around, we were due to meet at 9pm at a pub, but at 5pm she said "I'm so sorry I can't make it I need to babysit, but I'm free all week next week". I said no big deal and if she wants to meet up next week just let me know. Seems pretty reasonable to me but could still be a Flake. She then said once the kid has gone she would text me to come over, but she never did. I ended up going out and getting drunk that evening and for some reason I stupidly decided to call her at like 11pm, but she didn't answer. That was on Friday night. Monday now and I haven't sent any more texts and neither has she. From the outset of our texting conversation she would often take forever to respond, though I regularly do the same to girls so I understand. She said she got dumped from a 6 month relationship only like a week prior to us having sex, so maybe her old fella has gotten back in touch but she's trying to string me along in case it doesn't work out? I don't know. The thing is I am actually out of this girls league and she must know that too. I'm a pretty good looking guy, either a 7 or an 8. I wear designer clothing, my outfit that night cost in the region of £3000 and she noticed that herself. Not to mention I drive a fresh BMW and my game is playfully cocky and arrogant but full of jokes to make them laugh. This girl is a 6 at best, doesn't have that much money and her flat was a shit hole I'm not gonna lie, but she was amazing in bed so I would like to add her to my list of FWBs. I've kept texting to a minimum other than to arrange meeting up. My current plan is to wait til Wednesday to see if she messages me, and if not I will text her "Friday evening. You free?" and if she says she is I will suggest going to a bar for drinks. In the past these situations usually lead to the girl being rather obsessed with me for a few weeks and I fuck them 4 or 5 times until I get bored. This one doesn't seem to really care and it confuses me, I've had hotter girls than her go head over heels in the past.

What do you guys think?
