<human>: Give me the gist of the text in a nutshell

I currently am in a relationship with a girl that I love to death. I can honestly imagine myself marrying and having children with this girl.

She absolutely hates my ex. She has never met her though. I can't blame her though because my ex did screw me over and took advantage of me throughout our relationship.

I know I am completely over my ex. I would rather be celibate than get back with her. My current girlfriend doesn't believe that though.

We had an argument and long story short, I basically said that I would defend my ex in a particular situation which led to me saying I don't think 100% negative about my relationship with my ex. There were times when it wasn't terrible. My current gf said that I was holding on to my ex and even if there were positive times in that relationship, her being a shitty person and doing shitty things in the relationship makes the entire relationship shitty.

I don't feel like I'm holding onto anything. I would only hold onto the positive times with my relationship with my ex if I wanted to get back with her or maintain some kind of relationship with her, which I don't.  I don't want to associate myself with her at all. I'm just saying that I don't think it is entirely bad to think 100% horribly about an ex. Yes, it is bad that I defended my ex in an argument with my current gf because she is a shitty person, but just because I don't think 100% negative about my relationship with my ex, doesn't mean I'm holding onto that relationship.

Am I wrong in thinking that way?
<bot>: completely over my ex. Current gf doesn't believe me because I don't think 100% negative about very shitty relationship with the ex. I don't see why you have to see 100% negative.
