Stuck in comfort

[Snuffles]

Heres the deal:

Ran into an ex hadnt seen her in over month

was texting her and gradulay increase it to seeing her in person (have been busy)

She alolowed me to hold her and shit in public and when we git back to her place she asked if I wanted to come inside i said no because I had to get going
so I pulled her in and kissed her on top of the head, I dont really know how she took it because I got mixed signals.
later that night I texted her and she wanted to see me again.

Now I havent been able to contact her for two days and last night she seemed a little standoffish...

Any thoughts on how to increase the sexual tension and turn this into a close?
