Narcissist

I think my husband is a narcissist. Now I know a lot of people think that right after a break up but I GENUINELY believe it even though we are together. And I think he could possibly try to become diagnosed as he isn’t a completely terrible person he just does really awful and hurtful things. I love who he is when he isn’t treating me wrong but when he is treating me wrong (cheating, breaking boundaries, abusing, lying, manipulating, accusing) things are fantastic. Most of the things I listed are only previous mistakes that he has worked hard to fix. However he still manipulates me sometimes (semi-often) and he still lies constantly and even comes close to emotionally abusing me again when I catch him breaking boundaries of mine. I’m scared to bring this up to him. A few days ago we finally decided to go to therapy and so we are going to start that very soon, however how do you tell somebody you think they’re a narcissist? I’m bad at confrontation 😐 and I love him to bits I don’t want to hurt him
