Songs just make me think of people or times in my life.

I am not planning to leave my husband but if something ever happened to him, I would sell the house and move away from the town we have lived in for the past 26 years. Living in the same place would be painful from my POV.

In the case of other people who were once important to me--moving far away (either they moved or I did) did eventually make me think of them less. The trick is to have no access to them.

Your feelings will just have to run their course but try to see your ex as little as possible and don't read old letters or look at old photographs. Do new things. However, there are some people in our life we never forget. We can't take things back. Hugs.
