Girl I'm seeing on the 3rd date came over to my place, some making out but she flat refused sex. We slept and then when she got up to go I grabbed her cavemen style and guide her to a bj. She sucked for 10 seconds, said 'that's all you get' and then got ready and left.

In general i get this vibe from her, like she's doing this to make me chase. I'm thinking of just telling her I think our sexual values are not in alignment (I don't want to keep chasing, really frustrates me). Is there even a 10% chance the girl changes tack or is it certain that things will be finished once you drop an ultimatum?

Thinking this through, nobody likes to be pressured so it'll probably just finish things but I thought I'd ask as it also seems like an extreme freeze out.
