So when ex and I split 8 months ago he got to choose the days he had the kids, I have tried numerous times to get him to do every other weekend and now when it suits him he wants to take them camping but I have said no. He took them away for a week with his new gf in Feb and I was willing to be amicable about days but he hasn’t budged at all when I needed his help. I have said out days are our days and they don’t change.
