I'm aware of the support. To me it is really irrelevant. Did is A hardcore NGS. she already knows that. Yet, when he backs off she shows serious signs of being upset and temp checking. If it were only about money, I don't think she would do that, but only my opinion.
Again, I asked if HE wants the marriage to work. Divorce busting is changing oneself to make the other have a change of heart and remember who they love.
Focus on yourself. Give her some space. Stop divorce talk. Stop dating. Stop putting end points to the relationship if you don't want an end.
If the money thing is that big of a deal to you, then maybe modify the amount. But don't up and take it all cold turkey.
