1. He will go to great lengths for you.
There is nothing he would not do for you. He will start his car and drive for miles just because you want to eat at your favorite restaurant.
He will leave anything he is doing and come running to you if you need him. He will make sure you are happy and want to be the source of your happiness.
2. His confidence will have no limits.
After all, trust is the most important thing in a relationship. These are the foundations on which it is built. He knows you deserve his trust and will never question you.
If he does not agree with you, he will tell you about it because he believes you both are mature enough to reach a joint decision.
