Do you think he’s right?!

So I’m officially single and it was my choice because of many reasons. My now ex says something is wrong with me because I have said many times I don’t think I can move forward with our relationship. Before him I was cheated and left for somebody else and the man I thought who loved me told me he didn’t love me right in front of the women he was seeing behind my back. That relationship really put me in depression. It eventually I told myself I have to move on and pull myself together I still was ready to fully date again and it was two years before I got into another relationship( my current ex). He showed interest in my first and he was consistent on me being in a relationship with him. I told him my back story how much I was hurt and how I have trust issues and how I didn’t think I was fully ready because of that but he acted as though he understood and would never do such a thing. We was together all of 2 months maybe and I caught him sending messages to his ex. He still had her pussy pics she sent him when they were together. Huge red flag! Kept seeing him comment under females pictures like ❤️😘😍. It was to the point I was outraged because like really?! After all I told you and after all this time you tried getting me this is what you do? It took me awhileee to forgive him( I know stupid) he kept doing little dumb stuff behind my back. Now I got to the point where I don’t want to even be with him in that way anymore and I’ve been with him 2 years. I shouldn’t have been with him as long as I have been but I can admit I was dumb I forgive people too easy than I should. But he has been trying to prove to me that he’s not doing anything but the trust is gone I won’t ever trust him like I want to. Because he use to tell me “I’m not doing nothing” just to find out something. And I’m always thinking he’s doing something sneaky. I’m losing my mind about it. So I told him I think we should just call it quits and he refuse to break up telling me it’s something wrong with me. And I told him yeah it is something wrong with me I can never trust you but is it really something wrong with me for breaking up with you instead of making things worse? A relationship can’t work if there is no trust. I have never been disloyal to this man and he kept walking over me. Him doing what he did had some consequences to the point I’m ready to walk and he’s not happy about it saying I’m crazy and I’m starting stuff for no reason. I guess but I can’t be fully happy with him and it’s not fair to keep continuing on.
