Is it possible for people to view the relationship completely different?

I was with my ex & lived with him for 3 years. Our relationship is/was very toxic on both ends in my opinion. Every time we talked about our relationship afterwards he says that he still loves me & really doesn’t remember our fights or bad moments we had…

On the other hand all I remember is the arguments, the feelings I went through & I feel like I’ve fallen out of love with him. I don't know if maybe I’m being too hard on him but it’s hard to wanna retry with him when my memory is so corrupted. I met someone else who I feel wayyy more compatible with (not planning on dating anytime soon either) but I’m a little scared & blaming myself.

Maybe our relationship ending was my fault. Is it possible for two people to view a relationship completely different?
