LOVE...??? Unrequited LOVE??? One-Sided LOVE???

I wonder what is the true meaning of LOVE??? What is the true meaning of TRUE LOVE??? What exactly is love??? How to find our love??? When did it come??? usually, we wont realise when it come and suddenly you have a strange feeling in your heart... what should we do if we had an unrequited love??? what should we do if it was just one sided love?? what would you do if the person you love already have someone he love??? well,as for me,i would just keep quite about it especially when that person like my best friend...i would try to forget about him...what about you guys???hehe..^^
