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

Posted [this] in r/offmychest a couple weeks back. 

So I haven't been in many relationships. My first girlfriend was when I was 21 and in college. It didn't last that long. Fast forward 2 years later and I've got a full-time job, but frequent the local bars far too much to counteract the diminishing social life that has accompanied said job. I end up with this bartender who I think is attractive. She's got a child, but that doesn't bother me. There's obvious interest and we take things slow, but she ends it with a statement along the lines of "I think we are only in this because we don't want to be alone."

My problem: I can't get her out of my head. I literally think and analyze about everything with her. I know we didn't really "click." I know I should have noticed my attachment issues and that I was in the "relationship" for the wrong reasons. I was just so alone and enjoyed her company and the physical aspects of our relationship. I don't know if I'm just not emotionally mature, but I find myself going to the bars she works at and trying to act like everything is cool. We make basic small talk and that's it. She has moved on and is seeing someone else. Someone I've seen her with. Seeing that just makes it hurt even more.

I know I should stop putting myself in these situations (going up to the bars she works at) if I still have feelings for her, but I just don't understand why. She even said to me at one point that I need to "move on" and that we only dated for "like 3 months." I wish she could see my side of things. I just want to not care about her and not have to adjust my schedule to avoid seeing her. Maybe this is the wrong sub. Maybe I should address my self-esteem and attachment issues coupled with mild depression/anxiety. I'm sick of obsessing over her.
<bot>: Can't get over my ex of only 3 months. I feel over attached and keep putting myself in situations where I would see her. Don't know why I feel these things or what to do.
