Met a girl before Christmas at a party and got on well and escalated with her. She left the party before I could escalate fully.

The next week, she comes to a party at my place and spends the night. In the morning while saying goodbye she’s really driving home that she wants to see me after we get back to uni after Christmas and even texts me about it a little later after leaving.

Get back after Christmas and see her twice in a row at 2 parties. Both times she flirts with me heavy but doesn’t end up spending the night bc she “wants to play hard to get”.

How do you get around this? The way I’m currently doing it is just ignoring it and continuing to spin plates. However I would like to add her as a plate if I can. So how do you get past this unexpected resistance after having sex then the girl keeping you at arms distance after?
