I don’t want to say which person I am in this but hopefully I can explain clearly.
Divorced parents from 2 different countries (let’s say A and B) live in country C.
The child is on the pathway to very high level sports and will have to make their own decision as an adult about which country to play for (if it gets that far).
However they have received an underage call up for country A squad, and country B parent is refusing to support it- it will cost them to pay for travel there (once there the costs would be minimal).
There would be no impact on school and the club are supportive.
Country B parent’s objections are- they should be aiming for the country B team (this would be at a higher level), the cost when statistically they won’t be professional anyway, and why should they?
Both parents are well paid, and this can be afforded but with budgetting.
