Selective Memory

So I will be reading posts here on the forum or read something in a book and a memory will get triggered. A memory I either forgot or stuffed away. Is this selective memory or something and is that normal?

Last night I remembered incedents that I guess I just brushed off or choose to forget:

During an argument he would call me names like fat bitch or insecure or whatever. i'd ask him nicely not to call me namee especially in front of the kids. His response to that would be: "You can't tell me what to do. Quit trying to control me. You are not my mother." WTF?

N would tell me I am crazy. (Heres that conversation)
N: You are crazy.
Me: I am not crazy please please quit cutting me down.
N: See, that's proof. Crazy prople don't know they are crazy.

Also, we'd have an argument and he'd act like he was afraid of me. he'd hold his hands up as if to protect himself from me hitting him. Or he'd scream really loud so others could here "Get away from me. You are crazy and out of control. "

UGH! What they do to us is just ugh!
