I would group it all into one tip: Make an effort with your relationship. Like everything good in life it takes work to have a good relationship. If you make an effort to have a good relationship, applying thought and energy day to day, you will grow a healthy satisfying relationship.
This works well for women, not so well for men. For men, typically making a visible effort will cause your spouse to perceive you as weak and low value. This will only make things worse.
Reading a book won't reverse decades of cultural conditioning.
I recommend getting a Brazilian or Colombian wife instead.
