I know that you're propblay thinking:"why should I take a 14yo's advice on marriage?" You shouldn't,but I can guarantee that if you do exactly as I say your wife will be happy. But first things first:
Why should you make your wife happy?
Because a happy wife makes a happy life. A man's happiness must be when he sees his wife happy. And if you don't make her happy she might cheat on you,or kill you,kr both.
How to make your wife happy:
Make her stop nagging:
You know why your wife keeps nagging and shouting at you? She probably didn't do that before marriage but she does it now. That's because you don't do what she says anymore. You leave without telling her,she might tell you something and you don't even do it or don't do it immidealty.
Show her that you still love her
Many wives feel like their husbands might have lost interest in them after marriage and they're afraid that they might cheat on them. So show her that you love her. Kiss her when you come back to work. Hug her show her that you still love her
Buy her gifts
Even if she makes money as well,and even if she makes more money than you,you should still buy her a gift from time to time. Maybe a new dress or shoes that she wanted. And maybe raise the stakes a little bit more and buy her a golden ring.
Help her with some of the housework
I don't like Lenin,but I agree with him that housework almost kills women. That's why if you really love her you should do some of the housework. That would really make her smile
I can guarantee you that if you do all these your wife will be happy. I know it can be hard and requires a lot of work but her happiness is what matters! Thanks for reading
