I can grasp what you're saying. Doesn't mean you're going to be the one to marry her, but that you can see whether or not she possesses traits that would make her a good wife, in general.
I'm the same way with men, and it's saved me so much time/energy/heartache over the years. I can just sense in general if a man would be a good person with whom I'd want a relationship beyond casual conversation and/or a few dates. Then from there, I can tell if he has husband potential for me.
People tell and show each other who they are, all the time. It's up to the individual to decide what's important to them/what their needs are and be honest with themselves and those around them. I'm a 28 year old single female, in the South. Yes it's 2016, but people will still side eye and ask questions if you're not in a serious relationship/married at a certain age. I had the opportunity from one guy, three times, when I was 19-22. I said no. Why? Because he wouldn't have made a good spouse for me. There were core beliefs I would've had to compromise in order to be his wife, and there's no way in hell I could honestly be at peace with myself and build the marriage/home I'd want for my family (children, someday) by living a lie just to say I'm married! No, that's not me. We looked great together, got along for the most part, and it sounded good in theory. In practice, it was another story and it didn't take me more than 6 months to know we could only ever be friends and connect intellectually/creatively. No Harlem, no foul... he's now happily married, and all is well.
There are just traits that make someone serious relationship material (kindness, honesty, humility, for example) and then there are traits that each person needs from their partner to feel fulfilled. It takes time, and there's levels to this.
