he has had a crazy amount of accidents and speeding fines and has lost his licence.
His own fault entirely surely
Paying for fuel is the very LEAST he can do!
I bent over backwards to maintain dds contact with ex as I was the one that moved away first (he was army and also moved less than 6 months later) paid all the costs did all the graft. It was not appreciated by ex!
Reached a point I could no longer do it financially or practically and so I stopped - there were other factors too.
Result was he simply didn't bother to even try and stay in contact with dd not even by phone!
Why can't he travel to where you are and stay in a premier inn or similar and see the kids during the days? Or an air bnb and have the kids overnight there?
The harm of losing contact with a parent is greater than the risk of them suffering a 'distorted view of reality'.
Where's your evidence for this?
My dd is now an adult and well aware of what the situation was then as now and what her father is like. She has suffered but not at my hand!
Unfortunately, if one parent is shit the other one has to pick up the slack.
Not by knackering/bankrupting themselves!
