So if you are afraid of your husband's taking sannyasa, I shall not give him sannyasa order at any time. Be rest assured. Your husband is already a householder sannyasi because he has no other business than to serve Krishna. You can be living peacefully with husband and children and always engaged in Krishna Consciousness. One should become sannyasa by action, not by dress. In Bhagavad-gita it is said that any person who doesn't work for himself but for Krishna only is a perfect sannyasa and perfect yogi, never mind what order he lives in. That is the opinion of Lord Caitanya also.
