Oh wow, yet another relationship thread!

[Husar]

I've heard about saying it all with the eyes but.....saying it all with a hug?
Might you be reading too much in the hug?

There was a hug once, a memorable, strong hug, few years later they got married and still are.

As for the problem, uhm, it's up to her to realize that her boyfriend is a jerk, isn't it?
Surely there may be a chance for you to get her, but then you'll always have to be afraid that one day she will hug another guy like she hugs you and then you will feel a strong urge to kill him in order to protect your possession and......*ahem*, drifting away a bit, but I personally find it problematic, it's a problem I've had before.
On one hand you want her, on the other hand, do you really want a girl who switches boyfriends easily? It helps that he is a jerk, but then she should leave him for being a jerk, not because you convinced her to prefer you over him or so. Given that you aren't looking for a one-night-stand or similarly short-lived relationship of course. It may just be that she likes jerks anyway, because jerks can protect her etc.

There may be ways to get more info by making hints during conversation, then see how she reacts.

Or do what Monk says but then again you already did that.
