Your h will not crash until he's pretty much done with replay and he hits the real bad depression and withdrawal. He is still very much in the beginning stages of replay, what with his taunting you with talk of you divorcing him and him staying at ow's at times.
Please really read Deb's quote. This is really, really the time when he needs space and to make ALL choices on his own. Too much pressure, especially relationship talks, will send him to the ow and I know you don't want that. I'm also going to disagree with what vinlad has said at this time regarding telling him you love him unconditionally and God's love, etc. If you read in the book Men in Midlife Crisis by Jim Conway, a minister himself, he clearly states that many men during mlc turn their backs on God. IT's unfortunate, but true. There will come a time when you can discuss your faith and what God is doing in your life, but it's too soon to share.
