Regarding your separating from Nandarani, nothing should be done artificially. Nandarani is not different from you. She also seeks Krsna consciousness. Your household life is not repugnant; it is favorable. Do not separate artificially. When everyone is engaged in Krsna's service, there is no question of maya. I have got good estimation about Nandarani.
