I was somewhat in the same boat, I had a wonderful relationship with mymother who died pretty young. About 10 years later I ended up seeing a therapist who was about the same age. She was very caring and compassionate. There was a lot of maternal transference. When she consulted with my second therapist, she told her that she was definitely a mother figure for for me. I highly suspect it went both ways.

We never discussed the transference. We were both very careful to make sure I didn't get hurt. It was a great relation that allowed me to heal in many ways
