Background - ex and I split when son was 18 months. Since then he has him Fri - Mon, I have him in the week. He's 9 now.
Have always had a family based maintenance arrangement. Last year I lived alone and moved to another council house and didn't want to get the internet as felt I was too expensive and as was looking for a house with my boyfriend didn't want to start another contract.
Ex was unhappy about this as son has some homework to do online in the week (I would sometimes go to my mums) and also a wifi only ipad which they communicate via most of the time.
So he increased his maintenance by the £15 a month it would cost for me to get the internet.
Fast forward to now - he has just told me he is going to stop paying the £15 per month extra now as I have just bought a house with my boyfriend and my son has told him that we now have a full Sky TV package and therefore I now don't need him to pay for the internet for our son.
I wasn't expecting it to be honest and its just annoyed me a bit that he's just decided to stop this with no discussion whatsoever.
AIBU in expecting him to carry on paying this?
