Men dance on this and let their ego/bravado fill in the gaps on the fact they don't know their woman at all if she came into the man's life after the man got stable/independent (finished school/has a career/car/place/money saved). While most men are building their lives the women they end up dating was more likely than not hopping from exciting dikk to exciting dikk, and engaging in gold digging behavior through flat out escorting or using men in less explicitly transactional exchange of sex for dates, company, gifts, etc.
It's why I decided on GMB and set the deadline of no wife/serious relationships after 25 barring all but 1 or 2 boxes being checked. Modern women = damaged goods 8.5 times outta 10. If there's one thing I hate in life if people getting over on me, so I've closed the door on reformed whores, gold diggers, and woman who wouldn't give me the time of day now, but in 6-7 years would want me to take them out of the streets.
Life would be simpler if people accepted reality and made decisions based off truth. Dudes get married to women they know they couldn't bag before money/that are far more attractive than them/that they don't like as people and get shocked it doesn't work
