I actually think the answer to this is quite simple. They don't have to.

Time to apply for the D is 5 months overdue and I'm thinking about doing it myself. However, none of this was my idea so why should I.
I agree with the notion put forth, but would ask why are you thinking about doing it yourself. Do you want this marriage to be saved? If you do, then you have to ask the question of your wife. If you don't want it to be saved, just do it.
