  ο/η σύζυγος is equivalent to English "spouse":
ο σύζυγος = male spouse; η σύζυγος = female spouse
ο σύζυγός μου = my [male] spouse (i.e., my husband)
η σύζυγός μου = my [female] spouse, (i.e., my wife)

As Jonathan suggests, use ο άντρας (or άνδρας) for "husband", use η γυναίκα for "wife":
ο άντρας μου = my husband
η γυναίκα μου = my wife
