Since I am married, I will give some advice from that side:
- Protect her. That doesn't mean get in fights, but have some preparation and ability.
- Be a good dad.
- Never slide into beta. You are Alpha, act like it
- Always seek to improve yourself. Go to the gym, seek promotions at work. Take classes. She does notice.
- Never let her forget why you married her.
- Sex, lots of it.
- Provide. A man must to be a man.
