The dust has settled a bit now but I cannot get this, can anyone throw some light please?

When I had the light bulb moment and actually started to believe he was a big fat narc, I told him what I had come to believe and he denied it of course. It must be really painful to have it pointed out to you. So maybe my reaction or attitude changed towards him idk, but apart from everything being still my fault and me making him abuse me, why did he turn ice cold and decide to disappear on me? He was already pretty frosty toward me anyway, which is why I was searching the internet for answers. After my revelation though he backed away faster than the speed of light. My question is why did he do this? Could he only tolerate me when I was wearing the rose tinted specs?

He told me he was absolutely perfect in every way and that he had done nothing wrong, if he believed this to be so why would he bolt, instead of pressing home his point?

If I had felt my partner had falsely accused me of something I would do my utmost to prove them misinformed.

Why do they run when they get caught? I took the abuse for 15 years, always compliant and accepting, believing I hadn't tried hard enough. I asked him to be accountable for some of our problems and he didn't want to be.

He made me feel worthless like I was not worth the bother for him to try to put things right.

Was I expecting too much here ? If I could get this straight in my head I would feel a little easier.

Thank you.
