There are never blueprints in a relationship.
You can only be yourself. If you go into a relationship thinking you are going to fall in love then you haven't experience life. I have met someone thinking it was love and after 2 years found out that it was lust. Society says you can only love one person at a time but i have been with a person who compliments me in some ways and another person who compliments me but differently with both of them they make you whole. As long as you are true to yourself and open on what you want and handle you have the tools to be open to anything.
