<human>: Hey guys so I need some advice, about a month or so ago I made the tough decision to break up with my girlfriend of 4 years, things we're a little rough in the last year, we fought a lot, I wasn't too sure if I wanted a future with her, and I sort of avoided confrontation and communication with her I sorta gave up towards the end. At first after the break up I felt okay about the situation however for the past 2 weeks I haven't been able to get her out of my head,  I miss her all the time and ultimately I feel like I made a mistake. Yesterday around midnight she called me saying she was in the neighborhood and that she wanted to say hi. 

I agreed and at first things were normal, casual conversation, but then we got handsy, started to cuddle too, and eventually we started kissing everything felt so normal and it felt right. The feeling of regret felt stronger as time passed and it was hard not to feel like an idiot. Then we spoke about what happened between us and how we both missed each other, and finally she pretty much told me that if we're getting back together I need to have my mind made up about what I want. I love her, and I do want her back, we are supposed to talk again today. Anyways I guess my question is if I should take it slow, try to move on? My emotions are all over the place and I feel like I can't think straight, I miss her however I'm not sure if it's just me being lonely and vulnerable.

Can you summarize the given text in a few sentences?
<bot>: I can't get over my ex of 4 years, we met up last night, and now I'm not sure if it's me being lonely or I actually do want her back.
