Ex isn’t overly involved but does speak to the kids on the phone on messages (but rarely sees them) and doesn’t pay maintenance, often my kids will ask for money for things but I can’t afford to keep buying things so I will have to tell them no sometimes, I’ve suggested they ask their father for money for things sometimes rather than just asking me but then I wondered if that was ok or should I not be suggesting they ask him for money? (They are reluctant to ask him)
