You can never please her, she will always want more.
She is never yours, it's just your turn with her.
When you're single, you will always be free in every way another man in a relationship is not.
Never date her longer than 6 months, after 6 months she will always be looking for new prospects that are better than you to trade up.
Put every girl you date or see through emotional hell.
She can cry on demand to activate your protector instincts, so she can get what she wants.
Marriage is a fool's errand.
Never buy them flowers, candy, or anything. Make her put in as much work as possible then drop her. She will always come back for more abuse.
You can never tranquilize a woman so she can act the way you want her to. If you do manage to tranquilize her, it will only be temporary.
To win an argument with her, always ignore her, she will always justify her actions. If you do argue with her and win, she will just come prepared for the next argument.
Never get into long term relationships with women, she will always be in need of drama without it she will create it out of thin air. If you call her out on it, she will make you seem like its your fault.
