Return on Investment: A relationship no-no

People so often make the mistake of looking at romance as an investment with a return: "I put so much into this relationship, and I get nothing in return". As a businessman I love returns on investment. But looking at ROI in a relationship dooms the relationship, everytime. Forget the return. Love yourself and the other person and be happy about that. What they do is up to them and if it benefits you it is a bonus.
