So I met this girl on tinder. We hit it off really good and had really good sex on the third date. Like we did it four times that night in different locations and she was even thanking me in the end and telling me how really good it was. I intended to just have sex with this girl to get over my ex but I feel like I want her more often. So I sent her a text the next day saying that we should meetup again soon. She always answers slow but did the following day and said "We are going to" and that she really enjoyed it but she will be busy the next week.

I replied that I wouldn't have much time either and suggested Sunday and she replied a few days later with a different messenger explaining she had no money to reply by classic sms (this was strange all along but she is somehow an alternative girl and told me that she just recently started using smartphones... whatever). The point is that she said that she already has plans and maybe we should meet some other day.

I got the feeling that she is playing hard to get or is hesitant and replied "Alright, let me know when you are free". Do you think pulling away and waiting for her to come up with a date is a good idea here or should I suggest something in a few days?
