I've also been in therapy off and on for decades. One of the main side effects has been the growth of an ability to recognize abuse early and move on. In the beginning most of my relationships were abusive. Now, not so much. If I recognize the signs I move on, or, if it's at a work situation, I deal with it in a way that doesn't harm ME.

That took a lot of years to learn.

People often think divorce is always a sign of failure, but not all marriages are healthy ones and not all of them can be fixed. It takes two people to make a good marriage, but it only takes one to make a bad one.
