Cleaning Out My Closest

Have you ever had a moment when you think about all the guys you dated? For example, every person especially girls think about our last ex. It's a form of cleaning out our closet but in our memory. It's like that song "I'm cleaning out my closet". You first think about your first love and think how that will be if you would still be dating him or her for guys. Then you think about your second love, and then keep thinking about all of them. Later on the day or week you start thinking "why didn't we last". Some of do remember but then there are other relationships that you're partener dumped you. After a while of thinking all of that, you start to wonder why he or she dumped me. I wanna know what I did wrong to cause us break up. Majority of us would ask our ex but in reality we won't. We don't know how to ask. For example, when I was dating this American, he dump me after 4 months. During the breakup I asked him what did I do wrong to cause this breakup? Of course he said it was him not me. Then he said it was the distance and I don't feel the love I felt for you after a while. It's hard for us to understand maybe they weren't the one or maybe I should change that about myself. It's not easy but if we do ask our ex. We should change that fir our next relationship.
