Trauma Response?

I have posted this elsewhere, sorry if you have already seen this🫠 I’m just wondering if any of you lovely people have experienced anything like this? So I was a victim of DV over many years. Ranging from physical violence, SA, financial abuse and emotional abuse. I’m now in a relationship with the most amazing man, father to my children. It feels like we’ve always been together and like my past relationship wasn’t real. Am I crazy or is this my brain working in a mysterious way to protect me?
