My advice: you end convos you end phone calls you leave early (during kids' exchanges etc) you dont answer calls and reply via texts
All the above in an upbeat-friendly manner, not to punish him, not angry, just NOT needy. You are not looking for a chance to talk R to him, you are not looking for a chance to show him how you've changed. You just...are. If you do it a couple of times, it's a piece of cake.
