Okay so here's the situation:

I'd say my game is okay, not the best but its been getting me laid pretty regularly. My usual tactic is to go out at night, have a few beers (hate sober gaming at night) and get the numbers for a day 2.

On the day 2 I usually have sex with the girl that night, at least kiss closing. The problem with this one girl, and I want to get it sorted for similar girls in future, is that she has specifically stated that she is not a one night stand sort of girl. I know a lot of girls say that, but I actually got that impression anyway.

She is overall a solid 7, but she is boring as fuck. I can't try and close on the day 2 because I'm actually going out that night.

So my questions are:
What should I do for a day 3 to seal the deal? (cba going on any more dates than that)
How do I sexually escalate when she has absolutely no banter and would probably make it awkward?
Should I even bother with this girl at all?
