LOL. The thing Bill said about meds and stress is too true. Sexuality is a mental process. Sex is both mental and physical. IMO. couples go through periods when sex isn't high on the agenda for one reason or another. However, the loss of the desire for sex could be the result of other issues, unrelated to the individuals involved. If the loss is one sided, then there is a problem. If it's two sided, no problem. Some anti-depressant medication can cause function loss in part or in total. Both people should be in with the doctor when the decision is being made. There are other issues that have to be considered. Will both parties be able to live with the new status quo? Is it age related? Time of life? Heavy topic.
