Just out of curiosity I hope you are not funding him in any way being down there.

If he is getting even ONE PENNY from you, you need to cut him off immediately.

The less money you appear to be making the more pressure HE feels to contribute and the more his parental instincts will kick in. But you can't help him in any way down there. If he wants to be separated then he needs to fund that WHILE supporting his family all by himself.

I hope he is consistent with support payments to you to date. You shoudl NOT be helping HIM out in the slightest. If you are supporting him at all financially you are just funding his infidelity.
