You have a forgiving nature rainbow becAuse if this had happened to me I would be very reluctant to forgive or go back to her but that's my own stuff.
I am glad she admitted that for her holding your hand felt sexual because I am betting the feelings were all coming from her. People forget that therapists have sexual feelings too and it's so blooming easy to blame the client.
I wouldn't hold a clients hand because I know I would get confused with my own feelings. I only hold hands with my partners and if I brought that into the room it would feel sexual. That was a long time for you to keep trying to convince her, I would have been out the door long before that. I remember one of my tutors offering to hold my hand when I was struggling in class one day and I refused, she got highly offended but I didn't feel the need to explain to her why but that was more about her need to soothe me when I have my own ways of soothing.
