My ex won't help with our DDs (6 and 4).We split 2 years ago and because he couldn't afford a flat where the DDs could stay, they are with me 100% of the time. Up until now he has been told he can come round to see the DDs whenever he wants by mutual agreement but when he does it is always in my home - he never offers to take the DDs out even to the park or library and never has them overnight.
I work full time and often have to travel with work; rarely overnight but late enough home to cause a problem re childcare. My Dad and sister and ex-MIL help me with this. He says his work won't let him be more flexible - he works 8-5 and can't make it to our house until just before 7 - barely making it in time for the kids' bedtime. For this reason he says he can't commit to regular evenings when he can see the DDs and he won't commit to weekends either. He never phones to chat to them and has had a couple of periods when he didn't have any contact with them at all for 2 to 3 months despite my efforts.
How can I achieve more of an equal share of responsibility with him?
