KISS HER ?#@ Promise her anything and she still may want to leave you. Rightly so, you cheated and she has lost her trust for you. Her thoughts are probably "once a cheater, always a cheater" or "if he did it now, he will do it again." Trust is a bad thing to lose in a relationship. You may get lucky if she loves you enough to work through this. If you have no children together and since you are not married, she will probably see this as a clean break and will not come back to you. Take it as a lesson that you should never cheat.

Don't lie to her.
Just be yourself.

you can't. maybe he is happy the way he is.
If he really loves his girlfriend than don't even bother. Find another guy you can get. Don't bother trying to convince him otherwise unless you are sadistic, because he'd get rid of you quicker than you can say anything. Just stay as his friend.
Buy him a sports car :)
by letting her do her own thing
Stay faithful
