Why did you guys break up if your both in love? And being a girl I know if i loved someone and we broke up i'd be in my room crying like a baby, not out dating someone else especailly 3 months later.
If you have her in your life you may think it's only as friends but from your post you want her in your life so you can have that slight chance of getting her back. Apprently she has moved on with her life and I think you should move on. Find a new girl that you can have a good realtionship with and stop living in the past...The world waits for noone, why are you going to wait for a girl who's moved on.
Just my thought.
