"running off and buying a motorcycle with money WE do not have"......I'm very sorry, but you are still thinking WE...(like a married couple)..you are putting your children's welfare first...thinking about using spare $$ to send them to summer camp.
He is not thinking WE or family finances..he only cares about his wants and a new toy. Motorcycles...very cool for him, along with soccer and his interpretation of his new recovery.....like Dr. Suess says..."oh the places you'll go"......
it is hard to decide what is best, but you seem to be on different planes....You are WE and he is ME.
