Not being a man I can only give an opinion. But being raised by men and having brothers who did quite well at a young age I can tell you that what men want most from a woman is respect. He works hard for all he has and if he loves you he will share the world with you, but don't show him respect and he will feel like he has nothing and loving you wasn't anything more than a heartbreak.
I'm older and I hope the guy who contacts me is looking for intelligence, sweetness, a long term relationship, a future full of travel, someone to care about them and to be there for them in their old age, and hopefully the same in return for me.
Regardless of where a man is at in life or who he is - a woman who is able to emotionally & intellectually cater to his needs to reflects balance and harmony in his existence will always be desired and treasured by him.
As females we are blessed with insightfulness and natural emotional intelligence which are the tools that we can use to adapt to deal with people as well as life 's different situations.
Very simple answer---unconditional love, honesty and loyalty. Love that doesnt change in bad and good days, and that despite having the material things, they are not the focus, they are only the tool that makes every day an adventure so the unconditional love can grow. Maybe i am a dreamer, but i have all i want in life but these things----and very very hard to find these simple values in a woman that ignores the material, and wants the man for who he is, not what he has!!!
