Sorry if this is a bit of a ramble but I'm so angry at the moment. We are separating and still under the roof while house sale is going through.
Most days he leaves the house before we are up and comes home either when kids have just gone to bed so they are disturbed and all hyped up seeing daddy or comes home after I've gone to bed.
He has one day off in the week and works late shift next day and takes kids to school. Apart from that I do all of the childcare and looking after the house.
A couple of times I have gone out all day on a Sunday as he is home, just for some respite/catching up with friends and to give the children some proper time with their dad as things are strained when we are all together and I don't actually want to go out playing happy families anyway. (I do the weekly shop while I'm out so not exactly a full day of fun!)
2 weeks ago, a work thing came up which meant working at on a special project and staying overnight which I agreed to as it was the night he is home on his day off (I work 4 days pw). I got a barrage of abuse from him on text saying he had to go to work and I should have told him earlier as he had made plans. I am never able to make plans as he just says he has to work.
Today I go food shopping and spend time wandering round town and popped to my friends for a coffee. He starts texting me saying when are you home as I need to work. I must have been for around 4 hours. He had taken them out fruit picking this morning and also gave me a guilt trip for not going with them.
Apparently as I told him his week day off is 'his day' that's it. All other time is my responsibility. When I got home we had a row as I told him I shouldn't have to force him to spend time with his children and obviously work is more important.
I'm just sick of him trying to control me through the children, and then also attempt to alienate them against me as I'm the one who wants to split up our 'happy home'
The sooner we are in our own homes the better. How does he think that one school day a week is enough quality time with the kids??
I've suggested he has them for the weekend every 4th week as he does work Saturdays but should be able to get one Saturday off a month and he's still saying he doesn't think he can commit to it 

He tries to lecture me about priorities because I dare to have the occasional social life without the kids in tow, but he doesn't seem to get that him choosing to work pretty much 24/7 is worse! He doesn't get paid for all this extra time either!
