The 6 month D thing makes it clearer as to why he might be in a rush.

I set a timeline for myself - we separated in Oct. In Canada, we can fully reconcile for 3 months (incl sex) once a separation has occured. After that, the one year has to start again before a D. So my W and I reconciled in Jan, that gives me less than three months to work it out. Why the rush? I can't go through limbo for too long. My work is falling apart, and it is stressful on us all. For me, the 1st month together hasn't been rosy enough to change my mind to leave, but I'm here today still hoping.

If your state needs full separation, he might want closure. Ask him.
