Was I groomed by my therapist?

Hi! This is my first post, i’m sorry if there’s some mistakes, english is not my first language. I Just wanted to vent about this. I think I (F 23) was groomed by my therapist, and it didn’t stop until I was 22 years old.
When I was 13-15 a therapist who I was going because of depression, started to act inapropiately towards me. He was 11 years older than me. He started talking a lot about himself with me, telling me that “I was the only one who understood him”. When I was 15 he started texting me personal things, talking about his sex life with his gf, and he also said i was too mature for my age. I sended him pics, and he always talked about my body. I felt so special and listened, I felt seen. When I was 18 we started dating because I was now “legal”. But that relationship was so toxic, I always felt that that was what I wanted, because by his side i felt so so special, even when he was so manipulative. He only cared about me when I gave him sxual favors or stuff like that. But I liked it, i liked the attention he gave me, and at the same time i felt gross and used. I eventually broke that relationship 4 months after dating, and he began harassing me. It worsened when I started dating my boyfriend. I don’t know why but I couldn’t escape from that because he always made me feel like I was someone for him, that I was cared and loved for him, even though he just wanted me to have intimate things. When I was 22 I was abused by him so many times and he couldn’t care less. Everytime I wanted him to stop everything he just blamed me. And I thought that I wanted It, because I didn’t stop him. I felt needed everytime I said yes so I didn’t said anything. He only stopped when he was satisfied. I confronted him and blocked him because I didn’t want him anymore in my life.
I honestly feel so gross, and awful, everytime I think about It. Because I didn’t make this to stop or did anything to stop him. Sometimes don’t know if I was groomed, or it was something I wanted, and life’s has been quite difficult now, I can’t trust no one. I just don’t know what to do with my life.
Sorry for this, i just want to vent.
