the Corona virus

My ex sends me a message- how r kids

That's it.
 This is his first text to me in 2 years when he asked about the kids. 
It's been 2 years since I left him with my children. 
He never asked me once about them since April 16, 2018. 
First inquiry about the children. These are his biological kids as well. 

I asked-  why hasn't he paid child support? 

He says - let me know if you need something. 
I said - child support. 
He says- let me know if he can help. 

I said again - pay child support. 

And magically, he disappeared.
