<human>: So I've been dating this girl for six months and decided to end things with her yesterday because I thought I just lost the feelings I had for her. It was the hardest thing I've ever done simply because iv'e never been the one to end things and seeing her cry was one of the worst things I've ever experienced. She kept on telling me in tears how she wanted me to be happy and that if this was what made me happy then I should end it. She has a lot of feelings for me and isn't taking it the best.

I haven't had her off my mind since it happened and I feel like I miss her, I may want to get back with her and make things right but then again I don't want to hurt her all over again if things don't work. I still care about how she feels and seeing her be this upset bothered me. 

I'm also afraid that if I decide to move on that i'll never have something as perfect with anyone else. Or find anyone else for that matter. I hate knowing that I'm alone.

I feel like an asshole saying that I'm not overly attracted to her but she has an amazing personality, basically I left her because I thought i could find someone better, someone who is more fun and outgoing since I'm the adventure/go have a blast type person.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Left my girlfriend for no reason other than I thought I lost the feelings I had for her, now I miss her slightly. Should I go back and risk hurting her again or should I move on and try to find someone else?
