What is the single-word opposite of "misogamist"?

Question

A person who does not believe in the institution of marriage is called misogamist. But, what is a person who believes in the institution of marriage called?

Upon search, I found the opposites of misogamist as follows:

1. believer
2. optimist

None of the above opposites appears to be specific − that is to say, pointing, in specific, to the believe in the institution of marriage. The opposites appears to rather indicate an optimistic attitude in general. To make the opposites specific, one will have to qualify the opposites − like, "believer in marriage". But, that does not fit the bill of single-word opposite of "misogamist".

Answer 2

My ex-partner's sister was married to a man who had briefly been married, four times.

My ex, a bluff northerner with a unique British accent, from Sunderland, would roll his eyes and say of him:

'Laaaaaks weddin' kek!'

Meaning 'likes wedding cake!'

It always cracked me up, still does even now.

I thought it a great, oblique, and yes, sarcastic way to describe someone who is in favour of the institution of marriage.
