You have to accept that she has moved on. The relationship didn't sound to great anyway. If she can't trust you, then what's the point? Every relationship needs trust. And then she purposely made you jealous! She doesn't sound like a very confident person. If you'd like, try contacting her. A way for a lot of people to coop is by talking to this person that they once loved, since they've had time away from them they no longer have this idea of who they are so they can get a clear picture of who this person REALLY is.
