so now the deal is, since she's now attached, its easier to
continue to be attach and ask me to fuck off farr farr rather den
breaking up with the guy and patching up with me, right?
u all get my drift?
Attached doesn't you cannot potong jalan her.
But it's up to your ability if you can even do it or not.
If you have the ability to take her away from her bf, then by
all means go ahead and do it. If you don't, no point talking about
it and use the "I'm the kind of guy who play by the rules" nonsense
to exit gracefully like a gentlemen.
Ask yourself how much you want her and decide sensibly and
realistically based on your own abilities.
If she's married, then you must fuck off. 
And may the best man wins!
