Two DCs in high school. They can walk from my place.
The ex remains in the old family home which is either a drive or a train ride to their school. He expects me to pay half of their train fare for when he does not drive them (25 min drive). He currently works from home.
There is no money being passed either way between us but we 'share' the costs of school uniform, extra curricular club, top up for mobiles etc and any other things they need (like some clothes) that are not extras. Whilst he was not working I covered their clothes but he spent what he had heading to the pub or lots of wine at home (adding for context).
He is now back to working full time and has a couple of tenenats in the house which cover the mortgage and more.
I realise that it is happy days for me as the DCs can walk to school from my house but I really do not think I should pay half of their train fare to and from his house and school on the days they are at his. AIBU?
