Must love animals!!!
Must be more intelligent than I am.
Must love adventure.
Must be able to put up with me and my non-mainstream ideas and lifestyle.
Must not be clingy and need to know where I am and what I’m doing at all times.

Most? Character.

Compatibility, caring, faithful.

A spouse that is unashamed of, and completely comfortable with, their own wealth.

Looks not so important although I do have a "type". Politics very important. Money..not so important but must have means because I can't support him financially. Be kind...be smart...be funny. My ideal i suppose is someone i can talk to for hours and we make each other think...make each laugh...and then have great sex and fall asleep in each others arms.

Honesty would be the most important asset at this time in my life. (Obviously still recovering from a dishonest partner.)

Honest, kindness, and a fun sense of humor.
I've had money. Didn't really make the relationship worth much.
It's ideal he's handsome (to me), and we enjoy each other

I honestly believe a great, dark twisted sense of humor is what I look for, I'm not super materialistic, although money is important for a comfortable existence wealth not all that important, looks less important than a rapier wit and intelligence

Communication and fairness. Oh and not being batshit crazy kinda top my list! Money? No just help out a little. Looks? Eh, as long as I'm not turned off during sex. Personality? Such a broad and long topic. So many relationships are different, as long as we get along.

Most important is easy:

-An exceptionally high level of intellect. Smart gets better with age.

-Close second but also essential: She seeks the right answer, rather than seeking to be right.

These two characteristics in your partner and your life will be interesting every day and you will seldom, if ever argue.

The answer will be different for everyone....some things that are important can't even be put into words.
BTW, even if you find "the perfect person", there is still no guarantee for a happy future. Life happens.

Who needs a spouse anyway?

Financial security is one of the things I look for in a potential mate. Not the most important of course. Sincerity, honesty, intelligence, physical compatibility, non drug user, non smoker, mutual respect are some of the other things.

Wealth as defined by me..a wealth of humor, of smarts, of empathy...most importantly .
Eyes that are Alive...

To be honest, it's not one thing, rather all of the above.
I have to admit that looks to have some weight, but, intelligence, sense of humor, personality etc. go a long way as well.

Unearthly tolerance, apparently.

Compassion,calm demeanor,easy going,not argumentative,simple needs.

Personality, compassion, empathy, and love. Physical attraction is a smaller piece of the equation as I grow older. Shared interest and values are kind of important also.

Physical attraction is the trigger without it I wouldn't start a relationship. If the goal is a "living together" type relationship many factors play a role.

Loving each other everyday your together, and missing each other when your apart.

It's personal preferences. I wouldn't date a non athletic person since I'm athletic. I also wouldn't date a believer nor a conservative because I would have to practice restraint on the daily from putting a pillow over his face when he slept.

Honesty and good communication.

Compassion and empathy. All good things flow from those, and the details work themselves out from there.

In a word (possibly two words), common decency

That they don’t have another one or two tucked away somewhere. It happened to my cousin. She married a trooper in the Household Cavalry. He already had a wife and two kids about 100 miles away. She and the other wife became great friends, as did their children. Soldier boy lost his honourable discharge (he was still in the army when he did the deed), his pension rights, and stayed at one of Her Maj’s secure hostelries for a bit less than a year. He had no right of access to his kids, not that they wanted him to, and had a portion of his income (he has a successful up market chauffering business) garnished for maintenance until they were adults. I do go on!
