Sorry to hear about your H's attitude. I can sort of relate. My first wife left me with a 3mo and 3 yr old D. Now this is a mother leaving her babies behind. But I found out later she was on drugs (cocaine). I too think your husband is not thinking clearly because too is on a drug (the OW). All you can do is be there for your kids. They are the only victims in a divorce. Husbands and wives can and will move on but the kids are dependant on us.
My X never did come back. My D's are now 22&25 they have never met there "birth mom". As they put it. Hopefully your husband will get over the "high" he is on and come back. You don't know if this will happen. But you do know that your kids need you. Be there for them and don't worry if your husband is or not.
Take care Husband
And if I claim to be a wise man, well It surely means that I don't know
