its a cut throat game dude.. if shes got a boyfriend you should tell her to end things. If she wants more she will.. otherwise she's probably just down for the excitement of cheating and nothin more.

How about this scenario, true and ridiculous as it may seem in my life SPAM..

You meet a girl in school, see her almost every day. You hit it off so well over the months that you actually become nearly best friends and people always say "you guys are like brother and sister." This was the first time I've actually flirted without knowing it, no predispositions or motives it just happened naturally and you happen to be a PUA. Now let's say there have been two nights in which you hooked up while the boyfriend was asleep in the other room (already reaching immoral levels now.) Normally, this would be a hands-off, stop this now cause it will only cause problems situation. However, although I may have been living the single PUA life the past year (successfully) what happens when you think this situation is legit between the two of you and even though you are chill with the BF, you would rather this progress into something more exciting, maybe a bit more serious. Thoughts please?
