Another thought, along the soup kitchen lines. Many times there are walkathons, marathons, or races for some needy cause (hunger, AIDS, certain diseases, etc.). Sometimes the physical requirements for completing such a course are extensive, sometimes not. But even in the former case, volunteers are needed to staff the refreshment stations along the way. You two wouldn't be alone there, presumably. Often there are like 3-4 people per station (depends on the event, of course). That too, will take off some of the pressure and allow you two to interact as part of a small group, while still allow you to be doing something together, and for a worthy cause.
Just remember, however bad it gets, "this too, shall pass...!" :lol:
