Oh gosh, I know what you mean, especially in your marriage. When I used to fight with my ex -- he'd be saying stuff, and some of it I knew was WRONG, but I'd get so FLUSTERED, I couldn't manage to get the words out -- and my mind would be racing in 3 different directions, and I wanted to get ALL my points across, but I couldn't even get ONE across cause I was so upset! It made me so darned mad! And if I brought it up later, it would start the fight all over again! But sometimes I'd do it anyway! LOL
I know this stems from my childhood, because my parents used to fight all the time and it scared me something awful. Now, confrontation frightens me -- and I end up a blithering idiot!

And that makes me MAD.

Yes, I've been thru therapy -- years of it, darn it. LOL
God bless and please take care. Hugs, Lee
