No spouse should dictate to the other one what he or she can or cannot do. If the wife wants to take ballet lessons, is the husband required to also take the same lessons? I don't think anyone here would say "yes." The same with camping. If the wife wants to stay home for whatever reason, that does not then mean the husband has to stay home as well. He should be free to go if he so chooses with his wife's blessings. If he chooses to stay home with his wife, then that is his decision which he cannot blame his wife for any consequences of that decision.
