So last night was the first night stbxh was supposed to have kids. He had already Rang asked me to collect them from school as he hadn't changed shift at work, them yesterday morning text to ask what's for tea. Trying to rise above it for the kids I agreed to collect and sorted dinner. He proceeded to come to the house whilst I was out collecting them so I came back to find him drinking beer in garden . I made dinner then went to my room to do some work giving him some time alone with the kids. This had been the plan for few week until children 7,10 felt comfortable me leaving them with him and he would have them in family home whilst I stayed at mums. He has left home renting room nearby so can't have them there. I came down to find him asleep on sofa kids getting themselve treats. I ntold them to wake him and said he was supposed to be spending time with them, then I went back upstairs. Once the football was over and I had put them to bed he started massive argument stated I was spying on him making notes on his behaviour etc. He wouldn't have me in the house with kids again. He left stuffing my childcare for this morning when was supposed to be in work at 6am he was supposed to take them to school. I feel awful I don't want to leave kids at all at nighttime they have both clung to me since told of split at weekend. Son will especially struggle without me here is not close to dad and as u see from behaviour he doesnt really engage with them . How do I help kids and me accept fact they will have to spend time and nights with him without me.? Wish I could go back say nothing but felt he was being unfair on them spending no time with them. Biggest fear is he will move back in house he did threaten it in argument. House is in joint names still, although I am paying all mortgage amicable split going downhill fast
