Input: AITA? Backstory: My ex is a real treat.  He gave my older kids eating disorders, tried to brainwash the kids into urine therapy through scaring them that cavities were cancer and we had an epic divorce full of him demanding dirt, which I wasn't about to pay to excavate from the yard.  After the divorce he quit his job (making over 100k with benefits) to be a full time bitcoin trader.  Bitcoin dropped and he hasn't been keeping up to date on payments to me and I am still covering the kids extra expenses completely even when he says he will help.  

I got my older son a cell phone a few years ago and the ex would pay half of the bill, but my son lost the phone so it was turned off.  In June I got my older two phones and my ex refused to pay for any of the bills.  For Christmas this year I gave my younger son a new cell phone case that was military tested for drops and everything (I got the same case for myself) and he broke it while at my ex's house.  I told my son that he couldn't take his phone anywhere outside of our house without a case due to him being 11 and not the best at not dropping things.  

My ex called me very upset that he couldn't contact the 11 year old on his phone, I explained that he doesn't have his phone because he doesn't have a case.  My ex then went into a tirade that whoever bought such a shitty case was an idiot and the case was obviously shitty and how the purchaser should have done better research on cases and purchase better products.  I calmly said would you like to purchase a better case for our child's phone? Quickly he quipped that the children's phones were none of his concern and hung up on me. For the record my case is doing great and despite my kids dropping my phone, has not broken or been damaged.

After that phone call I told my children they are not to use their cell phones to contact (text or call) their father because their cell phones are not his concern, and he refuses to help with the costs. If they need to contact their father they can use my phone or ask me to contact him.  

My older son says I am putting him in the middle of our conflict because my ex won't take my phone calls and will take the kids calls. Which is true, my kids watch him not answer my calls when they are with him.  I said I am actually taking the kids out of the middle of the conflict and putting me right in the middle to handle all contact.   My kids think I am unreasonable.   Am I the asshole?
