Wife Begins at 40 (1988)

George and Linda Harper's 17 year marriage has gone stale, but George doesn't seem to be aware of it. When confronted with the problem, he gets a vasectomy, which solves nothing, so he moves out. Linda rearranges her life by enrolling in self improvement courses. Trying for an amicable divorce, they agree to use one lawyer and hire their closest friend. When this backfires, George attempts reconciliation by trying to seduce Linda on their living room couch. George botches the seduction due to the pressure of trying to perform well and due to the unexpected return of their son from a date. But it does result in their realizing they still care about each other...and that marriages need working at, need to be renewed and renegotiated from time to time and that their's is certainly worth a second chance. Based on the hit West End play.
