Don't even know where to start!
DP is basically a stress head! He works very long hours in a business he owns, we have money worries in that the business supports everything we own. I am a sham, But we manage. I totally get that this is a lot of pressure on DP
The problem is that when he is tired/stressed with work, he takes it out on me, and only me, an will somehow twist it round that I have caused him to be stressed, or I've not been affectionate enough ect
Once he has this head on there is absolutely no reasoning with him.
Today for example I asked him to have the children for an hour whist I went for a tour of a new job I'm starting tomorrow. He was too busy at the shop and went mad, I said it's not going to make a good impression if I don't turn up ect, now he isn't speaking to me because I've made him stressed 
If I try to explain that he is the only person stressing it's my fault, I'm in the wrong
Oh god I don't even know where I'm going with this but he is due home soon and I just can't bear it, I have to just smile and nod and take the shit he will throw at me and apologise
