GMTspouse & I are foodies. Before we met each other, GMT spouse was dating someone who was a picky eater. I was introduced to a blind date w food allergies. It was obvious from the start that the relationships were doomed.
I have an athletic friend who would only date buff, fitness types. I know some people who will engage in inter-faith or inter-racial dating, but not inter-faith or inter-racial marriage.
What is a must-have dimension in your choice of a life partner?
Mutual respect.
Sense of humor. I would have a hard time with someone who is too serious to joke, play the occasional prank and isn’t able to see the humor in every day life. 
ETA: And I have met people like that, my very close friend is married to one…that would be a non starter for me…
Has to be smart.
The good news is that H is happily married to someone not as bright as him ;).
Attractive, smart, healthy, and honest.
This is very shallow I will admit, but I am not attracted to fat men, and men who don’t care how they look. He could be the nicest and funniest person in the world, but if he is big, a slob and eats with his mouth open, NO.
I’ve only dated pilots. Would hate to think that was a requirement, but apparently it was.
Beyond that, I’d have to say kind, loving, funny and honest. NO cheaters. Those qualities are non negotiable.
Intelligence. Must be at least as smart as I am.
I don’t think I am that smart, so it wouldn’t be hard to find someone smarter than me.
Intelligence, helpful, easy going, not too fussy on most thing but particularly on cleanliness. I’m not a domestic goddess. Good manners overall as well as kindness toward everything. A good handy man. Family oriented. Love food is a must because I like to cook.
Good hair is important to me. I didn’t know it at the time but I had a dream and my subconscious told me about my inner consciousness. My husband still has a full head of hair, no visible grey yet.
A good sense of humor and couldn’t chew with his mouth open. I also would have a hard time with someone who let their religion dictate every aspect of their life.
Honesty, kindness, and courage - in that order.
I love chubby men. Chris Pratt before, was just as hot as after.
Unfortunately, my H has possibly 1 extra lb on him.
My dealbreaker would be someone unwilling or able to change & grow.
Personality: laid back (I couldn’t stand being with someone who was uptight about little things), supportive, kind, and anti-controlling (I can’t think of what word this would be… basically, I need to be with someone who is no way going to try and control my life choices- for example, pressuring me to change my last name with marriage.)
Other: My ex was mixed race so that doesn’t even register to me as part of the equation, but I couldn’t be with someone who was conservative or religious. I admire those who can be with people who are religiously or politically different from them, but I personally can’t.
Also- must love dogs. Absolutely non-negotiable.
No personal firearms, no excessive drinking or illegal drug use.
I’d want to check the following boxes:
I think I have to agree with @oldfort - a legit heavy guy would not likely be on my list. But who knows?!
No one here, besides me, put physical appearance as an important attribute for a romantic relationship. If you were single today, which I am, would you go on a blind date because, “he/she is intelligent, funny, kind, loves food…” and his/her physical appearance is never mentioned?
Intelligent, but not necessarily intellectual, I really enjoy most of the contractors I work with.
I’m not sure I could handle someone who had a deep need to be part of an organized religion.
I’ve never been attracted to overweight men, but I can’t imagine not loving dh if he’d ended up gaining a lot of weight. (He’s gained a little, but no more than I have.)
If you are in a relationship with someone already, of course you would stay with the person no matter how he/she looks (for better or worse), no more than if you would leave the person if he/she is not funny, intelligent…any more.
Well, I do follow a " religion", Im dedicated to good music, especially Pearl Jam.
It has only one commandment, " Don’t be an a__hole".
( but I dont know if I would call it organized)
