I don't know how to say this, and I know it is going to sound awful.
Basically two or three times my dh has reacted, or over-reacted to minor things. I playfully patted his bottom, so he slapped me on my arm hard. That was a couple of months ago. He was apologetic and said he got the wrong end of the stick. I thought ok, although I felt uneasy about things. Since then he hs been ok-ish. Then this evening, we had an arguement because he won't help me build the flat-pack wardrobes for our bedroom, and he punched me on my neck. I stormed off, and he has gone to bed without apologising to me.
It does sound awful doesn't it?
Could he really have made a mistake and not realise that he has hurt me?
