Hi Toiger
there is not legal amount of sensitiveness. Everyone is different and everyone had a right to be the way he/she is.

So the question of you are too sensitive or not had no reasons to be.

When your husband says so to you he really means " you are wrong and am I right". He is trying to make you feel wrong for what you are.

The question I would like to ask you is: how are things with your husband? do you think your marriage is in good health?
Because maybe that's the thing you should take care of. At least that's what I can guess from your post
