Who believes that love is a two-way street?

People say love is a two-way street, the reality doesn’t support it. It works best in a relationship if love goes both ways but in general love is often a one-way street. How many times in reality people love another as Forest Gump loved Jenny and have the object of their affection either ignore or care not that a specific person love them? People love other people all of the time but often never have that love equaled, making love a one-way street. Relationships have to be two-ways or it really won’t work, unless glued together with more money than Bubba Gump Scrimp. How did the notion of love being a two-way street ever get out there, and do you believe it?
