Alright, here is my immediate list of things to do. Immediately! And we have not had any contact today. This is combo list from AJM and Kassie
I will pick S up and take him to a kid place while H comes to meet us there so he can take over. And tomorrow, H picks S up from daycare and brings him back to me at 8:15. So that's all planned and we have no reason to talk unless it's an emergency.
Slow things down by detaching. It'll change faster if you change and detach.
NOT contacting H for a few days would be in your best interest. It'll confuse him too. He'll wonder why you are not contacting him. Let him wonder. That's a good thing. Stop trying to control him.
Stop overreacting to his disconnection. Instead make moves towards each other. Start giving him the freedom to be with your son. Alone. Without your interaction even if he invites you. Find a reason to not go over there immediately or at all if possible for a few times, and then mix it up and go when/if he invites. Let him have the alone time with your son. He deserves it. Let him struggle alone. Let him see what he's missing.
Your actions also speak louder than words. Stop using the words as much as you have. Do NOT ask about the relationship. Set a goal of at least three weeks that you will not bring it up at all.
