Yes, I was naive and thought I could change him. But all of this is because of him, not me. But I can choose how to react to this situation. It can be a lesson and it teached me some things about myself. It teached me that I can become way too attached because I never received love in my life, and I search for someone to love me, that I can be too clingy, too stubborn, that I want to change bad negative people tha abused me. His behaviour was abusive and wasn't right. At least I had some knowledge about abuse tactics (like gasligthing) so I instantly knew when it happened!
