<human>: 2 nights ago, I broke up with my girlfriend. Basics behind this are that I was not happy with the relationship, and I could tell that she wasn't either. Expectations were different on both ends and I knew that she wouldn't break things off, so I did it both for her and for me. 

But I miss her. 

I'm staring at a text message to send her. Just "Hey." I want to talk to her so badly. She was my best friend. I know that a romantic relationship will probably not work again, but I miss having someone to just talk to all the time. I miss her laugh. And I definitely miss hanging out with her. I feel like a piece of me is gone now. 

What do I do? I want to try to salvage the friendship part of our relationship, but I don't know if she'd be receptive, and if she would be, I feel like I'd be leading her on. 

I don't know. I'm sitting here regretting my decision despite knowing that it was for the best. I'm sad. And she was my support whenever I was sad. I don't know.

Can you condense the text into three sentences or less?
<bot>: Broke up with girlfriend because I need to grow as a person. Miss her like crazy because she was my best friend. Not sure if I should try to contact her.
