<human>: Well. I met someone a few months ago. Someone more gorgeous, more engaging, more passionate, more [insert adjective describing your dream girl] than I ever anticipated. I fell for her almost immediately. As she did for me. Unfortunately for me, not being the best boyfriend and also being used to a long-distance relationship (of 2 years), I more or less became complacent and boring and essentially stopped trying (my words) very quickly. She told me she didn't want to be in a relationship and that she feels like I just acted how I did when I first met her and the following weeks just to reel her in and then the real me came out.

So the advice. I know this girl really cares about me. If she didn't then holy shit she's good at faking it. I want to get back with her. She is amazing in every way and I've never connected to anyone so well before. I was honestly more depressed about this break-up than any other one I've had. What can I do to prove to her I'm not this complacent person and that I really am dedicated to our relationship?

<bot>: Found an amazing girl. I became complacent and essentially stop trying and girl dumped me. How do I prove to her I'm dedicated to the relationship and her?
