Getting over a toxic Relationship

How do you move past it once you’re over the person you no longer have feelings for them you don’t miss them you don’t want them back but you still just can’t get over all the bullshit and the stress and hurt? I feel like I’m crazy it’s been months and I still think about it everyday it’s like after an argument when you think of all the things you could’ve said except I just think about the whole relationship and all the times I should’ve stood up for myself but I either just didn’t realize he was manipulating me or I noticed but just took the disrespect without a word. I have trust issues now but it’s not that I think everyone is dishonest I know there are still honest and dishonest ppl out there like I always did but He was SO convincing so manipulative and I trusted him so much but he had a whole fake ass persona and was manipulating me the whole time now it’s like I don’t trust MY own discernment or intuition I feel stupid and humiliated and my pride has taken a major hit and I feel so pathetic I can’t just get over it
