<human>: So about 4 months ago, I broke up with my girlfriend of just over a year. Didn't work due to personality clashes and we moved in together very early. I feel the relationship didn't work because of some of my immaturities. I still loved her when I broke it off, but told it was for the the good of the relationship (it was, we agree on that now) But, for the past 4 months I have not seem to truly be able to get over this girl. She's just special. There is something about her personality and warmth that I have never seen  anywhere else. 

I'm quite happy at the moment as well. Work is good, I'm seeing some people in what are successful casual relationships. I don't feel lonely. But sometimes when I get home, I think about the fact that she's not there to come home to and I feel awful. I simply want her back in my life.

She came by just before to get the very very last of her stuff (I know) and I hadn't seen her in months. We got talking and man, I just felt so good. I feel like myself when I'm with her. She's seeing another guy exclusively at the moment, and I don't want to pull her away from something that might be able to make her happier than I ever could. How do I conduct myself properly here? How do I make it clear that I want to try this again, without being a brute and whisking her away?

Give me a shortened version of the text
<bot>: 4 months later I want to be with my ex after much thought, but she's met someone else who could make her happier than me. How do I go about this without being a brute?
