I agree. There is a point at which DB, or acting as if has to give way to practical decision making. It would not benefit you to give up your rights in this case and really think about it, if the only reason he's staying right now is because of a condo you will "let" him have to shack up with OW, is that good enough for you? If there is nothing more than that to your R at this point then I think it's time to take a step back. Remember, there is something to be said for all the times us LBS's have finally decided to let go, only to have the WAS start to get curious again.
I would say either way, D threat or not, you should not give in to this request.
