4 years back, I was in a relationship. I was busy with my studies and he was busy with his business. Lack of time for each other led to many conflicts between us and eventually we broke up after a 3 year long relationship. We both moved on with our lives. Today after 4 years of breaking up, he is in relationship with some other and I am genuinely very happy for him. Wherever I see them together, I don't feel any jealousy or anger or anything else, instead I feel very Happy for them both. No doubt She is indeed a great girl for him and I pray that they always stay together. But I am unable to allow any other guy to enter in my personal space. Whenever I try to do so, I feel that I am cheating on him. I feel uncomfortable with any other guy. I am not able to allow anyone to enter my space. I know that we are not going to be together by any chance, not today neither I the future. I don't wish to enter his life again but unable to move ahead. It is said that time heals everything but a long time of 4 years has also not allowed me to move on.
