Respect each other
Understandably, mutual respect is one of the essential preconditions of a successful relationship. Keep your differences in mind. Reconcile yourself to the fact that your partner needs more time than you for the same issues, or that he holds a different opinion.
In the case of you reaching the conclusion that you deserve the partner and that you could form an amazing relationship, first give him the proof that you are sufficiently mature and have adequate added value: respect his differences and all his wishes. Build your own as well as his life. Shape the sculpture together. And most importantly, be yourself. If you manage to do this, your own self-worth, as well as the worth of the relationship, will never depreciate.
