I was at the beach with a girl I hadn't seen since months, sitting and chatting. there was only me, her... and her bf

a few times she just stared blankly at me (with strong eye contact), like what girls do when they like you (I find that a bit strange, but whatever)

I was in the city only for a few days and it was the only day she was available to meet, so I couldn't have meet her again a few days later

basically I've 2 questions:
does that "staring blankly" thing really mean the girl is into you? What do you do when this happens? it always makes me feel awkward
would there have been anything I could have done to sleep with the girl? Considering she was with her bf, isolation seemed complicated

Definitely move on unless she's wife material. i am dealing with that situation now. very traditional, upscale woman, not sure what happened to our serious courtship--she doesn't date. saying that, i pursue other women and try to be in the background, which i think is perhaps counterproductive, other than a shout out every once in a while. upper class chicks can be irrational too, she won't express can't articulate her issues with me. i think it really boils down to a bad text incident early in the relationship. 
upper class refinement can mask bad female behavior, but it's lurking there somewhere. If I wasn't looking for marriage with this girl--we don't on that presupposition, I would have moved on when the b.s. started four months in the relationship.

what about that weird staring things that women do?

There seems to be some real weirdness or un-calibration going on (can't tell on which end exactly without more background), maybe she enjoys leading you on, maybe she thought it would be fun to make the bf jealous or show him that she has other options, more likely she is just used to plenty of "orbiters" & doesn't see you as a man/sexual option at all/etc...

It's not healthy either way and if she truly gave no heads up that the bf would be tagging along - or if you showed up despite her (thinking) she made it quite obvious in advance that it was a "friends" only thing & she was bringing bf.. or even if you did/could have a bit of a chance but just bad timing .... either way not worth it - move on!

It sounds like the staring blankly could be just spacey-ness, cluelessness, or boredom. In a "date" one-on-one it's ok to let the "awkwardness" like that drag out. If she was with a bf in a club night etc setting, sure, the eye contact could be a good sign she is into you, but in the scenario you describe- it could much more likely be weirdness/awkwardness on her (or your) part and/or trying to make the bf jealous or currently in a fight with him.

If you really thought you had a chance, day at the beach obviously is going nowhere- I suppose you could've transitioned to a night out and set up perfect logistics/gimmick so you might be able to somehow be the last man standing at the end of the night. Again she sounds crazy or just clueless so obviously not worth that kind of effort (with little chance of success).

I assume its boredom, chicks have constant validation now, with some mild curiousity. basically, if any western chick gives you any attention, smile, move eye brows in the top positoin as a signal. if she still acknowledges you, approach.
I think, since our societies are so individualistic and overworked, we usually avoid eye contact, also not dressing up on errands. I know I have missed such signals with this mindset.
