Long back story but basically I fled DV about 16 months ago with DD. I took the car and a bag of clothes and that's all. Exh cut me off financially and I ended up 10k in debt fighting all the court cases he kept throwing at me (I won them all because they were ridiculous but still expensive to fight) , evicted from homeless accommodation for not keeping up with my rent (universal credit refused me and refuge wouldn't take me in because I couldn't afford the rent without UC) with SS about to take DD into care because I was going to be on the streets. My parents stepped in and I went to live with them 250 miles away where I've managed to build a solid life for us.
We currently have a court order whereby once a fortnight he comes local to me for contact and once per fortnight I go local to him with DD for contact. Over lockdown the trains couldn't be relied on as they were frequently cancelled so we made an arrangement that she would stay at his for the weekend and I would do the drive each way to drop off and pick up as he doesn't have a car (I'd drive 250 miles there and back in a day, have a day off and then drive all day to pick her up). I was wfh at the time so I could do it, now I'm in the office 5 days a week and there is no flexibility to do this and also he refused to pay towards petrol because he said it came under child maintenance. For 2 months we've been back to the court ordered arrangement but with school holidays (DD just started preschool this Sept) in October I broached the subject with the ex that there was the possibility to have her overnight if he wanted. He does, but he wants me to do the picking up and dropping off as it was me who moved away from him. But the trains are back to normal and he's had long enough (and he earns triple my income) to sort himself out with a car if he hates travelling with a toddler so much on the train (which he currently doesn't have to do with the court order arrangements).
So aibu that he should either pick her up or drop her back off home if he wants her overnight even though yes, I did move from him and yes, I did pose the idea to him?
