<human>: Can you give me a shortened version of the text?

Just a week ago, my girlfriend of 7 months broke up with me over text. Text seems like a horrible way to end things.

We are both young, it was my first relationship, and it was everything special to me. We were happy and loved each other. As our relationship progressed, she became increasingly and increasingly busy. I wasn't experienced or mature enough to handle such a drastic change and I grew dependent/needy/insecure/however it was.

 Simply said, I handled her lack of time poorly. It got to the point where I asked too much from her and staying in the relationship made her life even harder. She broke up with me and I respect her decision.

I still have feelings for her. I feel like I've matured and I'm willing to do things differently so that I don't stress her out or demand as much.

I'm not sure what to do. I want her back but sometimes I feel it's best that we both move on with our lives. As for now, I just want to  be happy and not let this bring me down... How do I do that? I want to enjoy this summer as I head into my senior year, not mope around missing this girl. I've had fun with plenty of my friends but at the end of the day, when I'm alone, I think about her and it makes me sad.
<bot>: My girlfriend broke up with me. I miss her but I feel its best that I just move on. How do I do that?
