As regards your question whether it would be advisable and useful for you to marry again:  he feels unable to give you any definite answer on that point, as this is essentially a private affair about which you, and the friends around you or your Local Assembly, are in a much better position to judge.  Of course, under normal circumstances, every person should consider it his moral duty to marry. And this is what Baha'u'llah has encouraged the believers to do.  But marriage is by no means an obligation.  In the last resort it is for the individual to decide whether he wishes to lead a family life or live in a state of celibacy.
