I’m feeling a bit stuck and would love some advice. My ex and I have two kids together, and he lives far away (about a 24 hour round trip by National Express) with no car. He's unemployed and cannot afford the train journey and he's currently of no fixed abode, stopping at his sister's.
He’s recently messaged to say he wants to take the kids to see his family, which would involve them travelling such a long distance.
I’ve said no because:
The trip is just too long and difficult for the kids, especially considering my son’s medical needs (one has an organ transplant and on lots of medication that has to be given at certain times and the other is on a toileting schedule due to a permanent bowel issue).
My ex has a history of not being very reliable with the kids’ care. He doesn’t attend medical appointments, has ADHD and is extremely forgetful, and doesn’t handle practical issues like school or medical needs well. I’m the one who does all of that, and I’m worried he won’t be able to manage during such a long journey.
He’s also not really great at being present with the kids when he’s here for short visits—he tends to just text me for help when things get difficult. He's currently having access every 2 weeks in my home and today for example, he didn't take them anywhere so they are extremely bored and messing about. Instead of entertaining them, he messaged me to come and sort them out while he sat on his phone in the kitchen.
I’ve tried to be reasonable and flexible before, but I’m just not sure the kids should be put through such a long, disruptive journey when they don’t need to be. My ex is accusing me of not wanting to do something for him, but I feel like I’m putting the kids' best interests first.
Am I being unreasonable, or is it fair to say no to this trip? What do other parents do in situations like this?
