Ex is a good dad, pays a decent amount, is hands on, before Covid did fun stuff with the kids etc. He however only sees them once a week. Kids age 13-5. 13 year old has been going every other week as he had been wanting to see friends (Pre Covid) and just have some time alone without siblings which was fine, think ex was a little upset but understood. Now the other two 10 and 5 are saying they don't really want to go, they are bored there etc. I don't want to force them to go but ex thinks I shouldn't be giving them a choice and making them go as it's his only time to see them.
