The first principle in making a love relationship work is to love someone for who they are - not what you fantasize they could be.
Unqualified love is a gift given with no strings attached.
The problem with conditional love is that it is too impersonal. The answer is to do some attitude adjustment. You must fine-tune your thinking. When you first fell in love, you just saw each other's positive attributes. Only later did you start to see all of the negative traits.
