One late night call

He said that I had a great guy but he went and screwed it up...
He says that he still has feeling for me but doesn't want to hurt me....
He says he's scared to hurt me and the thing is I'm not scared of him hurting me.....
Something he and I notice is that everytime we start talking with each other again we end up dating.....
He and I have dated several times and then some should'nt we be over each other....?
He told me he looks back at the pictures of me....
I told him I did the same.....
When him and I are alone it always ends up with him and I kissing each other no matter if we are single or taken......
He and I look for each other in the hallways I thought I was the only one who did that......
I looked back at things I saved from him like notes and emails.......
He might not be the same as all the other gus but thats what I ___ about him.....
I know I shouldn't dwell and wait for him and I should just move on to other guys but I don't.......
I'm only causing myself pain and heart ache when I sit and think about all the memories I have of him and I together.......
But he says he still has feelings for me so I'm not gonna give up the hope....
I'm not gonna stop loving him I will keep going through the notes,emails,and memories.....
A question is how can someone be inlove with someone they don't even talk to that much anymore??
