Ok, I know that everybody hates long introductions so I'll make it short. In my university group there's a couple. She is soo pretty and energetic, and his not so god looking, boring, asocial and low energy guy. But they are together for like 6 months.
My question is how to steal her from him?

She gives me lots of IOIs, we have some odd relationship, but I can tell she could be interested in me. But the problem is social environment. It's a group of about 50 people, and I can't escalate. And she doesn't want to for obvious reasons to have some conversations with me boosted with sexual tension.
I think I should show her that I'm better that her bf, but I can't do my stuff at university. And it would be very odd to ask her to go out with me... Their relationship is so boring, they show no passion, when they meet there, they give each other small kiss, and that's it. So my biggest weapon can't be used - to light the flame in her...
So if anyone had some experiences with similar situations, I would appreciate any advice... Even if somebody stole your girlfriend, tell me how it went... PUAs of all countries unite
