Myself and my ex separated 6 months ago, it was my decision and one that surprised him so he took it quite badly.
Since he moved out, he rings the children every morning and evening, has them every other weekend and is now saying he wants them for tea one night during the week. I have no problem with him seeing the children during the week as long as he brings them home at a decent time, they're 7 & 4 and he keeps bringing them back way past their bedtime, tonight it has caused an argument as I now have 2 over tired children.
I also feel like he uses the twice daily phone calls as a way of checking up on where I am? I find myself clock watching waiting for the phone calls in the morning it's normally in the chaos of getting myself ready for work and them ready for school. I don't feel like I can freely do what I need too or want too as he rings. He even rang them at my parents twice a day when the children stayed over during the school holidays as I was working
He comes into my house (it is solely mine in my name ) walks around like he still lives here and seems to think he can dictate to me and ask me hundreds of questions. Am I being unreasonable in wanting some of the constant contact to ease up? The children don't have much to say to him in the morning as they've literally been to sleep and got up when he rings again! I know if I say to him about not ringing he'll get arcey about it. But he went on holiday abroad for a week and didn't even tell me 
Does anyone have any advice?
