Keys to a life long Relationship
1 - Discover yourself; favorite color, dress, food, destinations etc. That way you will know who you are and not expecting someone else to know who you are when you do not know either.
2 - Set reasonable standards that allow for changes with your development.
3 - Learn how to be accountable to those (one) you respects and trusts a lot
Prov. 3:5-6 - Trust in the Lord with all your heart
and lean not on your own understanding;
6 in all your ways submit to him,
and he will make your paths straight
