Treat your relationship as if it is important. When you enter into a relationship and decide to share your life with another person it is a big thing.
Most of us when we are about to make an important decision like buying a house, a car, a piece of land or making an investment we do due diligence to make sure we are making the right choice and the right decision. Yet we trust our lives to others without giving it a care or thought. If you think deeply enough we can all agree that our lives are more important than material things.
Relationships are important. We must take the time to find out who we are getting involved with before we go in too deep.
