So if she proposes does he get a diamond?
Seems only fair.

I knew if I proposed he would have a ring ....

This can be interpreted to mean that she would buy him a ring. It can also be interpreted to mean that "he would have a ring" for her. So, dunno.

So if she proposes does he get a diamond?

Of course not, but she promises not to have the police forcibly evict him from the house he paid for -- at least not during the first week of the marriage.

“So if she proposes does he get a diamond?”

He gets 75% of a diamond because she says that’s all she can afford.
