In your family life, if you find it difficult to render pleasing service to Krishna, then it is better to leave. If it is favorable, why should you leave? If the wife is devoted and all of the children are devoted, then why should you leave? If you find it not to be favorable, if you tried your best but you failed, then better to leave. Ramanujacharya did that. He played a trick on his wife and left. He tried his best. It is your duty; you should try your best to bring your wife on this path. But, if you tried your best but failed, then make some trick and leave.
