Discovered he has New Woman, now what?

I'll spare you the boring details of how I found out he has another woman - and has had her since one week after the grand finale D & D three months ago(the others were just the lead-ups). But finally, today I found some real evidence. Yes, of course it's very likely that he had her for much longer than that.

We were married for eleven years.

Despite expecting this behaviour from him - I have been on this forum for a long time- I was surprised by how enraged and hateful I still felt towards him. I keep striving for indifference and it never seems to come.

For those of you who have 'survived' the trauma of the other woman, or being the other woman, What can I expect now? From him? From her? Will this loathing of him go away? I can't stand the thought of him feeding her all these lies about me. It enrages me that he'll run through the whole gamut of his 'tricks' again. He's even written her a love song. (did the same for me in first month we were dating - god, it's pathetic, isn't it?)

So, a few more details - she has a three year old son. She runs her own clothing business. She seems like a very hardworking and together person.

He's going to suck the life out of her.

My speculations? He'll get her pregnant in the next year and then convince her that he'll make a great stay at home dad. [This is what he always wanted to do in our marriage, but I said no because he had secretly gotten credit cards THREE times and had racked up 60 grand debt and I told him there was NO WAY he was going to sit on his ass at home while i went out and paid it off! REsult: final D & D]

I have three children at home with me in Melbourne. He now takes off to Sydney every weekend. No phone calls to his kids, nada. How on earth does he convince the NW that he is great father material? God, the web he must be weaving...She must be paying his airfare....

Anyway, what sort of garbage will the assclown throw at me now? What pitfalls can I avoid? What is the typical behaviour now? Could I actually HOPE that he will take off to Sydney and abandon his children for the NW? [Someone please say YES!!]
