After some perspective here...
ExH moved 3 1/2 hrs away. He earns a high 6 figure salary so he can afford to rent a flat/drive/travel. Used to have EOW plus 1 night. New relationship, quickly remarried -> Cancelling weekends, contact chipping away. Now says can only manage school holidays and the odd weekend because work/distance/whatever. He is making me sound the unreasonable one for suggesting that seeing as he is free as a bird to do what he likes with his weekends, maybe he could drive down to see the children that he brought into this world. History of gaslighting and fuckwittery. Just after others' experiences, what arrangements work for you?
