Should I do it for love or because it is a good Idea?

i have been engaged for 4 years now. the only reason it has been that long is because immigration has given us the run around.She is lebanese and is now a refugee in the UK. We have been trying to get a fiancee visa. we only saw each other for two weeks out of the year. 6 months ago (while I was staioned in Korea) she said that she wanted to break up and that she didn't even want to talk to me. A month ago when I got back to the states and started to tell our parents of what she had said she decides to change her mind ( I think because of pressure from her family). So now I am at a cross roads. I don't think of her that way anymore after 5 months I got over her. But we are a good match. We would get along I guess you would say but I don't "love" her. what do you think I should do?
