I read this earlier but couldn't reply. Fo beat me to the punch. Lead by example, don't try to punish him to try to make him understand the pain you went through.
Yes, it is very difficult to see him travel suddenly. Shoot, my WW had more sex with her OM#1-4 in the 6 months following BD than we did in our entire marriage. And I'm sure she threw her resentment for me into her desire for them. Meanwhile she's getting child support while I sponsor it all.
The world is a horrible, horrible place to be. It's not H's fault. He's just the guy you happen to be with while you learn how disappointing marriage is compared to the dream we used to have.
