<human>: I broke up with my girlfriend of a year and a half last week. It started off great and then I started to become unhappy. We hardly spoke, hardly went out and she had nothing in common with me. But in the beginning it worked. 

She was my first "real" girlfriend so of course I still have feelings for her, I've spoken to her about my thoughts and nothing changed so I decided to break it off. Now I'm sat here, wishing she was here. Is this because I made the wrong choice? Or because I just miss the company and hate been alone. I'm afraid of been alone.

I just don't want to settle down, I love her to pieces but I just don't see us spending our lives together. I planned on doing it a long time ago but every time I looked at her I couldn't bring myself to do it, so I thought that maybe if I wait out the bad, the good will come eventually and I may become truly happy. 

I always thought about what it'd be like with another girl, and after consoling with a good friend of mine, they said that if I was having those thoughts in the first place then my girlfriend isn't the one. 

Does the pain of missing her but at the same time knowing it's the right thing go away? I'm feeling as though it isn't...

Could you distill the essence of the text into 1-3 sentences?
<bot>: Finished girlfriend after a year and a half as I was unhappy, now I miss her but know it was the right thing to do.
