my birthdate is december 6, 1973, my husband's is june 13, 1974, what are your predictions for us?

is it lucky for us to have another child(a boy)? will my husband be promoted this year? we often have misunderstandings as husband and wife how may we avoid having frequent misunderstandings? Is my husband being unfaithful to me...hope to hear from you soon....thank you and God bless..
