At least you're here and seeking support and wisdom
Here in Aus we have the benefit of having to wait 12 months before you can get divorced.
Anyway, it seems your hubby seems to think this woman has a future with him...by introducing the son. But you haven't mentioned if the OW has left her hubby? Is she just maintaining an affair or left as well. If she's still with her hubby at this point then there could be some big let downs in future.
But I'll assume they ran off together. Remember the advice of the LRT. Well I cannot emphasise it enough. Stop contact unless he contacts you, don't cry, get emotional, listen to him, even if it pisses you off, and say ok thanks and hang up... or whatever.
The hardest thing all this crap does is drag us down. We have to find the real selves again. Not to 'win' them back, but to be the strong independent people we once were. Sometimes we want to get angry... I think sometimes we need to release things, tension, and alike, but not at them. It just re-emphasises to them that we were nothing in the first place.
I think the best advice is not to fight it. If he wants a divorce, let him. If he wants you back in a few months or years, its up to you, but you can always get married again. Plus once I spoke to our court registry, and some stories that came out of there... whao! It will be interesting to see if he can do the divorce papers himself. My ex couldn't and rellied on me to do it. I baulked once, and she through a stupid line at me saying that 'I never keep my word' lmao. ie I can't be ***** you do it.
You don't really have to see him during the divorce. Use emails or letters.
There's plenty of info about here so have a look around
