Women only have as much power over you as you give them. If a girl is coming off as entitled and you don't feel she deserves what she thinks she does, then refuse her, either directly or tacitly.
Last week a girl I tried to game a while back shows up at the music event I was attending.
I've not done anything to get on her bad side but she played a labrynthian girl-game that was both hard to crack and tiresome. I moved on, kept spinning plates, etc.
Anyway, she catches me a bit off guard when I bump into her, smiles, offers a big hug. I'm not feeling it, but not being a total jerk, I give her a half-hearted hug, tap on the back and proceed to join my buddy. Turn back to her and continue on with what I was going to do anyway.
A few minutes later she comes by our table and puts her hand/arm across my back/shoulder. I look over my shoulder at her with the expression, "Uh, the adults are talking, do you mind?" and returned to talking with my buddy. She spent the rest of the evening dancing near me or in a place where I could see her. Ignore
My point is that this girl presented me initially with "some" interest, played too many games, and I eventually lost interest. But she thinks she entitled to my continued friendliness and attention. Sorry, but it don't work that way, girl. You've earned nothing. In fact, you have work to do if you ever expect a normal and pleasant interaction with me again. I'll not be a jerk to her, but no warm friendliness and fun, flirty chatting. That boat has sailed and you deserve and will get nothing.
Entitlement is simply unearned expectations. Don't give them anything they haven't earned and when they act like they want/need/deserve something, ignore and/or refuse without explanation, just like you would a child.
