That's the real problem. It's very hard to tell what you have, so you have to run these women through several tests, and even if she passes, you still have to come with the expectation that people are capable of anything. Mentally, you have to be ready for the woman to walk at any time, but when you have one that grinds for you to an extent that other women don't, you have to show her appreciation.
For example, you have a woman that respects your leadership and doesn't constantly second-guess you. She isn't going out all the time. Her female friends are decent. She doesn't have 'male friends'. She doesn't mind cooking and cleaning. She has enough education to where she makes her own money and doesn't really ask you to pay for anything. When you've been down and out, she's been there to support you. You ran her through the scuttle-butt test, aka you've seen what others have had to say about her and never did some man come through on some 'she's easy' or she's 'everybody's friend' tip. Obviously these women are rare, so if you find one, then what a blessing.
I believe an exclusive relationship to a woman should be a reward and she has to pass a stringent test. Just as there are signs to cheaters, there are signs of decent women. Even with that said though, we are all human and anything can happen, but sometimes you have to take a risk to win.
I keep telling dudes that going out with extroverted chicks is lame and only for sexual relationships. Only good women that you can legitimately wife is the humble, introverted, pretty face, in-shape women that will do anything to make you happy. Problem is, there are so few of them left in America with the facebook/ twitter/ instagram age that you have to travel

That clubbing/ going to bars/ "modeling" crap is not normal. Society is brainwashing men into thinking that these chicks are chicks that you must settle down with or marry.
