The biggest mistake that man take

"Playing Mr cool"

The biggest mistake that men make is that they put women on a pedestal and treat them like they're queens. For example, man date woman in first class restuarants which they have never been.

Women have flaws, just like men do, and when you treat them like some perfect goddess they will take advantage of you because they know themselves that they're not perfect so in their minds any guy that treats them like they're perfect is obviously weak and lacks confidence so they will take advantage of such guys by walking all over them. It's best to love a woman but also hate her a bit. The hatred that you feel towards her flaws will keep you from treating her like a goddess, which in turn will make her respect you more because she'll know that at any moment you could leave her for another woman, so she'll try hard to keep you with her, rather than if you treated her like a goddess; she'll think she has the upper hand.

However, spoiling your woman is a good practise but men must also consider playing it according to the rules  50/50. "You spoil me ,I spoil you."
