When you’re deciding whether to plunge into a marriage, don’t ever make the mistake of thinking you’re marrying the person your partner is going to become, once he or she finally grows up.

Said : Matt Bai, National Political Columnist, Yahoo News, in his June 9 column "The black hole within Donald Trump." 

He said this in context with key Republican Party leaders endorsing Donald Trump for the Party nominated presidential candidate, who totally believed Trump when he promised “I can be more presidential than anybody. I can be a totally faithful husband. You wait." 

[When you’re deciding whether to plunge into a marriage, don’t ever make the mistake of thinking you’re marrying the person your partner is going to become, once he or she finally grows up or finds that perfect job or stops making meth in the basement. The only person you’re marrying is the one sitting right in front of you, and while some people do improve over time, only a fool would count on it.]

"On second thought, this advice probably comes too late for the Paul Ryans and Bob Corkers of the world, who were exactly this foolish when they wrapped their arms around Donald Trump and said: “I do.” But you know, they never asked," he added.

Commenting on Speaker Paul Ryan's refusal to un-endorse Trump, even after admitting that later's remarks about a Latino judge were racist, Matt wrote : "Deceived spouses always throw good money after bad. It’s hard to look in the mirror and admit you were had."
