Unfortunately, from what you've described, I have a strong suspicion he will eventually regret this divorce.

A very close friend of mine is dealing with this. After 28 years of marriage her husband went into MLC, wanted another woman, and divorced her. It was really ugly with a lot of fighting on both sides. She moved away and has a new life, but lately (about six months after the divorce... and the divorce took a year) he has started calling her for really off-the-wall things. All of us who know both of them think he's finally agonizing about the whole thing. So sad.

You keep strong Olive. Make sure that hook he's throwing out is actually catching him. You are wiser, you started going through the pain sooner (OW is a cushion or a haze helping him avoid the pain, eventually he'll have to deal with it), so ultimately you will heal more quickly than him.

There is no arriving, ever. It is all a continual becoming.
