I am glad interjection understands.
Marriage is hard work. Any interpersonal relationship is, due to competing personalities, needs, interests, etc. No matter how compatible 2 people are, they are different. G-d made each one of us unique, and the Talmud attests to this profound humanism: “For if a man strikes many coins from one mold, they all resemble each other, but HKBH, fashioned every person in the stamp of the first man, and yet not one of them resembles his fellow.”
We’re told that it’s as difficult as kriat yam suf to make a shidduch (Kasha zivugon shel adam ke Kriat Yam Suf), but I’d say maintaining a marriage may very well be more difficult.
And a person doesn’t discuss their attitudes in general on a shiddukh resume. They usually give information about education, accomplishments, religious weltanschauung, interests, goals, etc.
As for me, it is very important for me to be Dr. Daniel ben Ploni, and that is a personal goal I refuse to relinquish. And I would like to travel, live in Manhattan, spend more time in learning, and do humanitarian work prior to marriage. It is not always possible to do these things when you have a wife and kids to support, hence “constraints.” If I decide I want to move away to go to medical school, all I have to do now is hug and kiss my mother and shake my father’s hand. With a wife and kids, you have to be grounded and settled down in a community.
