A lot of women look for security out of a man. They want to be in a situation where they can quit their job outright or switch to part time hours so their man can pay for most or everything. I've worked with women long enough that I've seen it happen like clockwork. They get pregnant, take a leave of absence. Come back and work for a year, get pregnant again, leave again and then come back with reduced hours.
If they can't do that with you, they don't want you. To these women, a man is a surrogate parent to THEM. Men need to have a "father" energy. In essence you have to be better than her in every conceivable way and make up for all her deficiencies. You can't be too outwardly and obviously better though because then she feels insecure and resents you for being in a position where she may have look like you're settling for her. If she feels you can do better, she'll think you are. She'll think you're cheating on your business trips or when you work late. She'll think you don't spend enough time with her. She'll eventually push you away and then claim that you "were intimidated by an outspoken woman"
Its an old dance. I can tell this is what will happen with ol girl. She'll find a nikka with more money than her, he may or may not commit, but it won't matter because her unsaid expectations and her insecurity will sabotage the relationship and put her right back to square one.
Relationships benefit women more than men, and women hate being alone or in their own company more than men do generally. A man who appears normal(looks healthy, has no major financial problems, mentally well adjusted and good social skills) is often single because he wants to be. A woman who is in her 40s with no man is single because she can't keep a man and is unwilling to be realistic about her expectations.
You can't be 6'4 and refuse to date a man under 6'6. Thats less than 20% of the population. You can't be earning 100k a year and refuse to date a man making less than 200k. Most people don't even make 80k.
