I spillled something on the way into the kitchen last night. I meant to mop it up before DH got in but forgot about it.
When he came in I had my earphones in on low, in one ear, so as to still hear the children, who had a friend over. They were playing upstairs and saw or heard nothing, fortunately.
DH saw the water on the floor and assumed it was dog wee, which is fair enough. They do sometimes mess in the house when he is in alone with them, so I can see why he would think that. When he started whinging and ranting immediately I put the other earphone and turned up my ipod, which I will fully admit was very childish.
Whilst ranting he stepped towards me to drag my headphones out but slipped and his hand hit the side of my face. I am willing to accept that this was an accident. It didn't leave a mark, but it shocked me and I jumped.
Now at this point I believe he should have immediately apologised and explained that he did not mean it. He said nothing but continued ranting until I asked who the fuck he thought he was hitting me and asked him to leave the house. He did say sorry but it was "Sorry but you jumped, that's why my hand caught you. Sorry but if you'd have listened to me. Sorry but if you were not being childish it wouldn't have happened. Sorry but....." Excuse after excuse. Switching the blame to me.
This is what I am uncomfortable with. I heard excuses time and time again from my dad to my mum. There is no excuse. It's only "Sorry. That was an accident and should not have happened"
After this I refused to speak to him and left the room. He followed me in the kitchen and blocked my path. He kept asking why he would hit me. I eventually replied "I don't know. You tell me, you did it". He then picked up the potato peeling knife and slashed his hand and walked out sucking his hand and telling me I had stabbed him 
I knew he hadn't drawn blood. I regularly accidentally stab myself when peeling veg, I know that knife is not sharp enough to cause any damage.
I used to self harm as a teenager and my sister is seeing counsellors regarding self harm and a failed suicide attempt, which is why I find this action particularly sick.
I am more than willing to accept I was acting childishly with the headphones, but it's no excuse, is it? It was not my fault and I am not over reacting? I kind of know I am not, but I am doubting myself.
I am leaving on Saturday afternoon. It's gone too far and gotten too bad. There is no way back from this.
