Even as it is now though - it does not sound like much but imagine this:
You are in the living room, your husband walks in after a night's sleep.
You say "G'morn. Did you sleep good?"
He says "Shut up"
So ... An hour or so goes by with nobody talking.
He says "Will you get me some water?"
You say "alright" start getting up but you hurt a little so sigh a bit
He says "Well nevermind then! I will get it! Don't worry about it!"
You say "I was getting it..."
He says "Yea - whatever. No need for all that complaining."
You say "I hurt a bit, that's all"
He says "Can't you ever just drop it - just go get the water!"
So you go get the water
Later, you are sitting there and he tries to walk by you - gets upset because he needs to walk around your feet (that are already up against the chair)
Another few minutes or so pass and a neighbor knocks on the door - you don't answer quick enough so he asks "Can't you answer that? Don't you know how to get up? Are you too lazy?" (All while he is sitting in his chair not trying to move
Then after a bit you ask him if he wants some more water while you are up "NO I DON'T!!!"
That is just the first half of your day. Later you get cussed out for asking questions or glancing at him wrong or if he happens to have a bad experience that day - along with the yelling and stand offish attitude.
If you try to hug him, "wtf are you doing now?"
If you try to kiss him, he moves away
If you say "I love you" - its received as an aggravation
Him saying "I love you" n kissing you good night is seen as a chore

Imagine that being your daily routine

It wears you down.
You start thinking maybe there is something wrong with you and this is all you deserve...
