My ex and I are still in love…five years after the breakup. We have both been in serious relationships since then but reach out to each other every few months to let the other know our feelings haven’t changed.
We now live in different states and have our own friends and careers, making getting back together very difficult. The unwillingness to let each other go is preventing us from completely committing to new relationships and causes insecurity in our new partners. What should we do?

Have you ever been through therapy where you’re told to remember why you got together in the first place? In this case, you need to remember why you broke up. There was probably a very good reason. If that reason still exists, you need to cut this ex off, for at least a year. One of you has to drop the end of the rope and stop playing tug of war with your emotions. It will feel wrong for a while, but try. Don’t make a big thing out of it, just block their number, emails, texts, etc. Let them bounce for a while. They’ll get the message. Sometimes you have to do something that feels bad now, so you can feel better all the rest of the time.
