So I've been seeing this girl - we've gone out a few times and whatnot. The first time I took her out he both drank some and I ended up going down on her but the f-close wasn't going to happen. Since then she has no problem sleeping at my place our having me over, but she doesn't take her pants off. She pissed me off last night because she gave some guy her number right in front of me (which I think I am using to my advantage). So she sleeps at my place last night and I don't touch her and sleep with my back to her. She had to go to work in the morning and "forgot" some of her shit at my place. My intuition is that she'll now want to make it up to me or whatever. How would you handle this situation?

Lay her in her place, she's trying to walk all over you man.
She left stuff there so that she has an excuse to come back and see you.

Next time you're getting busy, if she rejects, do a freeze-out. (look this up if you don't know).

Hopefully she'll want more from you and you can continue.

She had last minute resistance (LMR), so you have to overcome that.
