Ways to win over a chick who has a BF

I got a nice looking girl that told me she likes me but she doesnt want to leave her bf cuz they been together for 4 months. The thing is they live 1000 miles apart and have only seen each other once since december.

i consider my game to pretty effective but I cant find a way in just telling her how I feel. She says if were supposed to be together it will happen but im trying to speed this shit up

im just looking for suggestions
