Any ideas on how to get her to leave her boyfriend for good?

Thats the sweetest thing I've ever heard. My best advice to you is tell her everything you just told me. Explain to her exactly how you feel but don't beg her cause that would stress her out. Just talk to her and let her know your there for her. If its meant to be, it'll work out.

Dude one thing just be Mr. Wonderful try to surprise her with little stuff. Try to take an interest in everything she says and does he is I Florida your here in Texas he won't suspect anything he can't get his hands on you or anything if her family hates him show her that you too were meant to be sorry this may not be too much help but I hope you get her I'm if you like as you said you like her as much as you say you do you won't give up till you find your fate well let me know what happens.

Ask her out. If she says, "you know I have a boyfriend," just say, "so what; let's go out anyway. " Just say, "come on; let's go. "

Don't criticize her boyfriend to convince her to go out with you. Try not to mention her boyfriend. Try to get her to forget about her boyfriend. Give her attention and get her to think about you by spending more time with her. Say as little about her boyfriend as you can (hopefully none at all) and just charm her with your personality.
