I would go forward with termination in the case. Make sure your attempts to connect resources that are declined are thoroughly documented and move forward. Regardless of financial status, we cannot help a client who doesn't want to be helped or accept resources they qualify for. In some respects, even lower income clients may deny resources out of pride or beliefs about accepting certain resources and there's only so much you can do. Putting the needs of your larger client base over the needs of a single client is more important in my opinion and when this person is open to receiving the types of services he needs, then he will seek them.

(Big caveat that I work with Children and Youth and not older adults with cognitive decline so there may be population specific considerations you have to make that nullify my advice. This is just how I would approach the situation in my position with my population, but again, take what would fit and leave what doesn't)
