What does "I want to be friends. . . . . for now" mean?

This is just a random question, but its the line That most guys use on me. I have always wanted to know from a guys opinion what it means. They always tell me that, they don't want to mess our friendship up, but they leave it with an ending like "For now". What does that mean?
