What could his therapist be suggesting???

[2chiquitos]

Ex has been seeing a therapist since DD 6mos ago. I have seen positive changes in him. He is more himself, not completely but a lot more than 6mos ago. He is working on fixing his relationship with people he has hurt along the way. (our friends).
However he continues to see OW. And he makes it a point to say he only wants us to focus on coparenting our kids. Yesterday was the first day he he sounded hopeful. He said, "IF we continue (separated)....blah blah blah". I don't remember what he said after cuz that's all I heard! It's the first time he says something like this. Really blew me away! But going back to his therapist, what could he be advising him?!?!
