I need adult advice please...This is a long question please help me!?

I think you are being too jealous. I still have stuff from my ex fiance and girls I have dated since. I don't keep them because I want to remember her, but more of where I have been. I don't take pictures at every turn of my life. I have every movie stub for each movie I have gone to since 10th grade because they are memories to me. I have dated girls who had family pictures with their exes and I didn't have a problem with it. It was part of their life, and its not my place to say get rid of it.
