I agree with pps that there will quite probably be "something" that reveals itself over time.
People who aren't avoidant have the ability to compromise to get and maintain the relationship.
So they might go for someone who isn't perfect looking, or doesn't have the "professional" job, or already has kids.
The relationship and living in and thriving in a family environment is the main thing.
I was at a workplace where there was a guy who was one of thise European Earth Father types - he was happy to be sole financial provider to a family unit (wife already had 4 children of her own, and they had one together).
Some of his colleagues were a bit snide that his wife had "snagged" a guy with a good job and got a SAHM role.
But there was no magic - he just was a big family guy. He wanted the kids running around, that's what he got.
I can compare that to guys who want someone slim, childfree, "professional" vibe, good dresser, independent, pays her share...
They project the vibe that they just want someone who matches a particular image, and they won't cope or are difficult if partner doesn't match the script.
You cannot imagine them compromising massively when children come along, you'd be expected to produce the perfect offspring, meet your share of the bills and snap back to action ASAP.
If they're super good looking or very rich then maybe they'll be ok.
But if there's no pre-established connection, and they're just meeting strangers the kind of woman they want probably will be dating others.
