If he’s marrying her, he will be embracing the suck later down the line. No way is a 19 year old physically attracted to a 57 year old man unless he has wealth and status, which isn’t really a sound basis for a happy marriage in the long run. Once she’s been with him long enough to claim alimony, she’ll divorce his ass and shack up with a much younger man nearer her age.
Given Morrissey’s track record, I’m guessing he will be unfaithful long before his fiancee.
