A good man/woman will increase and help you multiply the resources you have, a bad man/woman will diminish your resources. This is why choosing should be done carefully.
This is a problem for both adult men and women because choosing the wrong partner can make someone more stressed throughout their life. A good partner can support their progress and will be at the forefront of providing support. Many married couples end up separating, generally due to incompatibility, and mistakes stem from not knowing each other well enough when deciding to marry.
Choosing a partner carefully is important because we will spend a long life together. If a partner is incompatible and unable to accept each other's strengths and weaknesses, it's best not to pursue a more serious relationship, as this can have a detrimental impact on our future lives.
