Just take care of yourself. If you're spending time with your son when you would rather be doing something else you're not as present as you would be otherwise, so take care of yourself and then be present for him.

Your wife's EA is a symptom, not a cause. You'd be in the same situation regardless.

In my case exW had a long EA that ended, then she had another EA that ended, and then another EA which I finally found out about just as it was ending. I thought "great, now he's gone, that's over, and we can work on repairing this relationship!" Which we did for three years, then she had another EA/PA.

It's a symptom. If the guy was gone but she's still feeling the way she is, she'd just seek out another guy, and believe me they are not hard to find.
