Thank you to both of you.
I just finished reading The Divorce Remedy last night, but I feel like my case isn't quite applicable.
His frequent traveling has made him used to not seeing me and his kid very often. I know he misses the kid, but not so with me.
I wonder if asking him to leave was a mistake. It was just too painful at the time having him here, while he was communicating with the OW.

When he asked for the divorce, he was surprised I wasn't in agreement. He thought we could jump straight into being best friends and coparents.

I'm trying really hard to be responsible with money now. I'm saying and doing all the right things. It's just too late for him.
