Don’t Expect Her To Change - Don’t expect them to change. People change because they want to, not because you want them to.
Don’t Make Assumptions - The biggest relationship mistake I see young men make is thinking that “women are this way” from all the stupid “forever alone,” “Hey, aren’t girls crazy?” and “Hey, listen to this story about my crazy girlfriend” stories that float around.
Try To See Things From Her Point Of View - I would have to add empathy to that list. Being able to place yourself in your partner’s shoes and see things from their perspective is very important when diffusing fights or disagreements. The challenge is to get your partner to also do this on a regular basis.
