Well, the child support comment would probably just make him mad. I don't think I would respond in that way.
I would probably respond by reiterating that you love him and still want to work your M out. Or just don't respond at all. If going semi-dark pushed him away and he is still @ the house, at times even, just be pleasant & loving to him. Act "as if" nothing is happening as far as D goes.
If it comes up, you can tell him, like I said above, that you love him and want your family to stay together.
Does that help at all? I'm surely no expert here
