He was registered with one of the main membership bodies. Happened less then three years ago so fits their criteria for investigation (I've checked),
I was a in a very bad place, very vulnerable. He manipulated me and convinced me to take courses of action I was not comfortable with that had significant impact on my life.
Promised we could be friends and then proceeded to have a weird 'friendship' with me, went for coffee etc straight after finishing therapy.
I long suspected that the 'friendship' was so he could keep an eye on me after I decided I didn't want to be his client anymore. So a deceptive friendship that was basically unboundaried therapy that I had not consented to.
I'm feeling fine now just annoyed that he might repeat this behaviour with someone else. There is more than I have said here but that's a very brief summary.
