All Women are naturally same in a way. They like to show off, and they are never satisfied. They compare what they have with other women (including you

)
If you marry a woman, you have to be a man and keep your game up. You cannot let her down. Make her feel proud of what she has
That's not simping, that's being a man. If she leaves you, make her feel she missed a big part of her life. You need to be financially stable, and you need to have respect for yourself and she should feel that.
As a man, you should never let your life revolve around her. Keep yourself independent at all times. Let her feel that

and make her depend on you (it is not always about money

, it could be anything, including emotions and feelings).
Finally, find your own happiness. Women are good while you have sex. Other times they are a big headache

they always complain because they are never satisfied and they are always worrying about things.
You get her a gas cylinder, now she will complain about something else. Learn to ignore such things. (But always do the needful when necessary)
Marriage is not easy

very stressful..but it has its nice things too. Have kids. You will feel delighted when you see them smile

also make your wife happy. You will feel happy.
It all depends on your attitude and mindset
Always love her. (If she loves you back). And most importantly, do not cheat
