I went to therapy after multiple disasterous relationships. I needed to figure out why I kept picking partners that ended in disasters, correctly surmising that since it kept happening, the common denominator was me.
I addressed my issues. I stopped looking for a new relatonship. I was happily living on my own. That's when I met my second (and still) wife. Very little drama in nearly two decades.
Unironically, at work I still have projection issues. My therapist has a job for life...
