How old is your son? Has he hated every girl you've shown an interest in? Is he pulling a power move? Look at the big picture here. Kids can manipulate. If he's out of the house, he's just being selfish.

It might be that he is very possessive over you, or worries that he will lose you. Best ger him into therapy or go together.

OP - Very foolish move. Unless there’s a serious problem with the fiancé, never let your children rule your love life. Years later they will be grown and you will be alone. … Many children feel threatened for affection by a love interest. And no matter how wonderful that fiancé or girlfriend is will create problems. … The best way is to make sure that: (1) Children understand you are in charge at home not them. (2) Dad will always love your children, but you have needs too of a romantic relationship. … My Dad had problems with my sister and his second wife because sis was used to being the “woman of the house”. I had problems with my son and my fiancé because he was prone to always testing the limits.
