TL;DR
Recently I have been getting into a lot of fight with my girlfriend, and I love her so much. But she thinks I am still not over my ex and I constantly thinking about my past every single day. Which is truly not the case. Me and my girlfriend have been together for almost 2 years and I plan to marry this person in near future. We had a shaky start in our relationship which makes her think that she is my rebound but it was love at first sight and I have been head over heels since then.
Now she wants me to prove that I love her and I have put my past behind me. How can I do that. Kindly help me out, as I love this woman more than life itself and I need her.
