<human>: Can you succinctly summarize the text in 1-3 sentences?

It's been 4 months since she broke up with me. I met her friends, parents, and coworkers. I thought things were heading in a positive direction, but it suddenly ended. She told me she didn't have any romantic feelings toward me and I can understand that. After all I would rather a girl tell me that after 2 months than 10 years.

I've dated a couple girls since her, but I can't get her out of my mind. I can't stand to be near any other girl and don't know why I am still holding on to her. I just want to have closure, which I thought I already had, but I don't know what to do.
<bot>: I dated a girl I really liked for a awhile, we broke up and I can't get over her. What can I do?
