How to suppress emotions, like a man?

- Never talk about it with anyone. In groups talk about only serious subjects like economics, politics and sports. Condition oneself.
- Set expectations and live up to it - calm under any circumstances, always be "rational". Act as if you know everything and have any situation under control.
- Anger and Pride are allowed since it matches with the expectations.
- Any signs of breach of these, fight back / avoid / ignore so that the moment passes and one can forget about it and move on.
- What is past is past, never analyze too much, think too much or talk too much.
- Talk about objects, not subjects. Don't get into details, keep it short.
