How would i be able to deal with get my ex to quit sending me crappy, pernicious messages?

Our divorce online in Texas https://onlinedivorcer.com/online-divorce-texas is practically finished, we have 2 children so we can't not talk.. however, about once per week he send me a lot of writings yelling about how all that I did was terrible and how I'm never going to be upbeat, and so forth I'm certain a significant number of you know how it very well may be.

I simply need him to stop yet regardless of how often I say "don't message me except if it's about the children" he proceeds to message me.
