engaged female is a fiancée engaged male is a fiancé
the man because he should be a gentleman
In the US if a man is entering into an engagement with a woman it isn't traditional for the man to wear an engagement ring. The woman is typically the one who wears the engagement ring.
Unless it is a family heirloom then the young woman can keep the engagement ring as it was a gift to her of the young man's pledge of love. A man who has given an engagement ring to his girlfriend and either one breaks up then a man should not give that engagement ring to another woman that may come into his life. Women would not want some other woman's engagement ring. If he still owes money on the ring then it is entirely up to you as to whether you wish to give it back to him or not.
It depends on who broke the engagement then who gets to keep the ring. If the woman breaks off the engagement the man keeps the ring. If the man breaks the engagement, the woman keeps the ring.
the man's brother-in-law
My wife is a man and he/she hates engagement dinners.
The man gives the engagement ring to the woman.
Oh, dude, you should totally call him a "clampman." Like, it's not rocket science. He's a man, and he's got a clamp. So, yeah, "clampman" it is. But hey, if you wanna get fancy, you could go with "Mr. Clampington."
His fiancee.
This depends on who broke the engagement. If the woman breaks the engagement, she has to return the ring. If a man breaks the engagement, she gets to keep the ring.
There is only one ring a man should give to his girlfriend. Engagement ring and there is no other! Reason being.... Imagine the misunderstanding if she thinks you proposing and your not. A man should only ever buy one ring and the engagement ring should be equivelent to a months' wage. Traditionally it should be a single solitare prong ring presented in a red box.
The term is a cuckold.
