Huge step there, Jo - on his part. IMHO, your job is to stay in the same place doing what works, and let him come to you.
I might expect some tests, irritability, disappointing behaviors - all to see if you're changes stick or not. Be prepared to stay positive. I also wouldn't offer any more of the ILYs to him until he earns it by dumping and declaring his dumping to you of OW2.
