My underlying case is likely far more complex and not worth reiterating here, but make sure you and your attorney discuss what happens if he doesn't respond (do you need discovery or can you just take a default and be done), if he doesn't participate in discovery (do you have other ways to get the information you need), if you have to obtain subpoenas, if you have to file motions to compel, and motions for contempt for violations of the motions to compel, the costs for these things, and what a default judgment (if he truly doesn't participate) looks like for you. Does it give you the relief you seek?
Also consider, if he truly doesn't want this action, if he is giving you money, what happens if he stops paying you? How long could you go without money? How much does your attorney estimate it would take to get temporary orders to get the money flowing again? The way people behave before litigation begins is often different than how they behave after, particularly when they are conflicted or mentally ill.
These things sound simple at the surface, but there is more below. It may be that they don't tip your scale one way or the other, just make sure you know what you are getting into if you commence litigation against someone who sounds truly conflicted and may not move from point A to point B in a logical fashion. Read some of HaWho's account of how her husband behaved during divorce, Gerda's or Pax's. Mine filed for divorce and then completely stopped communicating with his lawyer to the point where I was getting fined by the court for the case not moving forward and not in position to get a default (since he filed and I was asking for more than I would get on default).
