Gentlemen, a harsh rule:

If a woman wants to leave, open the door for her.
Don't beg like a dog afterward. Chasing after her is only humiliation, and no woman respects a pushover.
Cut off communication and focus on yourself:
• Go to the gym.
• Make money.
• Socialize.
• Create an environment with men who share your vision.
No tears are shed for someone who leaves.
Focus on your work.
