Abusive ex sends text to say he's reducing maintenance payments for our son. Maintenance was £224 per month agreed through solicitor in 2014 and has never increased since. I've recently heard from my son that exes girlfriend and their baby have moved out due to too much fighting. I'm assuming this is now him splitting maintenance to cover another child so think it's ridiculous he's talking about belt tightening Covid restrictions. Thinking I probably won't bother replying TBH. There is a lot I could say but engaging with him is probably not a good idea.
