Share residency 50:50 with ex but ex's job and social life means DCs are often here more than they are there.
No maintenance paid in either direction although ex still claims CB but I let that slide.
Because DCs are here more often and because ex doesn't bother with things like after school activities when they're there, all their clubs and hobbies are arranged for days when they're here. At the DC request, I might add.
Given the above, WIBU to ask that ex pays half towards subs, equipment, etc?
