I have posted about this before but it has now come to a head.
Basically, my dc (12 &10) stay 2 nights per week with their dad and he allows ds2 pretty much unlimited screen time. This involves using a laptop ex needs for work (he wfh) but he allows ds on it all the time as he seems incapable of getting him to do anything else.
He has got a quote to have a laptop built that would take all of ds's accessible savings/pocket money (about £350) as well as about £150 from ex's relatives. I had already discussed this with ds and told him I wanted to see him saving for about a year and then I would pay half. This is because he spends any cash he gets (savings are mainly from my dd payments) on absolute shit and I don't really want his account emptied. I also don't want him spending it all on a laptop that ex is having built as I don't trust ex and I'm also not happy ex is just doing it because he can't be arsed to parent him. I also suspect ds would be encouraged to leave the laptop there when he comes home so that ex could use it, especially if it turns out to be better than ex has atm.
I've emailed ex and said ds won't be spending the money now and he has emailed back telling me I'm 'a cow', 'a nasty piece of work' and to tell ds he (ex) has cancelled his laptop. I don't know how to put this to ds. I don't want to criticise ex to ds but I know ex will curse me to high heaven when they are there later this week. How do I deal with this? I can't think of anything to say that won't involve saying ex is out of order. Ds knew perfectly well he wasn't allowed to spend the money at this time...
