Journaling.

No R talk, crying, begging etc for 8 days now. I know this isn't a long time but I'm proud of my efforts so far.
My main problem is I need to learn when to STFU so I have really been working on it.
No physical contact for 2 days which has been great because, out of sight out of mind.
Now I mentally feel back at square one.
Sent ex a text saying son got his fingers stuck in the door jam and my dad had to take the door off to free him. I missed a couple or calls while playing outside with the kids and next minute I see a police car pull up in our drive way (ex is a cop) and out he hops and says that he was to see how S was seeing as I didn't answer.
He started to have a conversation with me about his morning at work and said that he would come and stay tomorrow to see the kids.
What do I do about this?
Should I say that he needs to just pick up the kids and take them back to his parents or should I continue to let him see them in our home and stay here?
