"Do You Remember The Time"

Michael Jackson said it guys and you know it. Do you remember the time we fell in love? Well, thats not what todays focus is. Todays focus is confusion. I had an recent event occur once and I want to ask the audience their opinion or theory. I was over my ex crib and long story short feelings came back that I haven't had in years. All because I was "remembering the time I fell in love." Now nothing happened of course, but I didn't realize that I had a soft spot for her at time until I was arguing with her about the situation through text because I was working (another fatal mistake). So after telling her that among other things, I told her I didn't want to hang with her anymore because its painful and I am setting myself up cause I am confusing myself. Now I have not spoken to her since and the way the conversation ended, sounded like she wasn't pleased with what I wanted in the end cause it seemed dumb to her and that I was possibly overreacting. Am I wrong for this? I mean really. I made a decision based on past situations and experiences by not just myself but others as well. So I did what I felt was best for me. Someone tell me what the deal is.
