<human>: Can you give me the gist of the text in a nutshell?

At the beginning of high school I met a girl. We started dating shortly after and we were together for two and a half years. It was my first girlfriend, and we lived many cool things together. But we always had some trust issues, she has never been fully open with me. 

In recent times some things started to bother me more, because even talking to her, nothing changed. It wasn't something serious, she did not cheat on me. But I was no longer feeling well. She seemed to put me in the background. I was no longer a priority. 

So I decided it was time to end. She said I was abandoning her. I felt a little guilty and a few days after I went to see her, we treated each other like nothing have happened, but when I was leaving she said she had not yet sure what she wanted. 

I gave her some time to think, but she always runs things. She said she would see me one day, but a few hours before she said that could not go anymore. We talked again recently, she said that just wanted to see me after the new year, because had things to do with her friends. 

I thought she really was not giving priority for us and I said that I wanted to see her before the new year. Since then, she stopped responding to me and apparently does not want to see me. 

Despite all the mistakes, I still love her a lot, but I also feel that I am not giving value for myself. I want to get over it, I know that there are thousands of other nice people, but lately I've been depressed.

Sorry if I made any mistakes with grammar. I'm from Brazil.
<bot>: I broke up with my girlfriend, regretted, tried again and she stopped to answer my messages. I feel unable to overcome.
