I know what your friend is going through...I've been there but my story was different. People who can't stay with that certain someone think it's the end of the world. Unrequited love is the most painful when you are deceived or betrayed by that person. He or she may not accept it at first, it would be much easier for her if you give your love and support. It was very difficult for me, to face the facts and I got over it 2 years later. I endure all that with no support at all, and I'm still here. I don't believe that love can hurt another....those relationships are false they are all one sided. Because of that one person who is selfish and insensitive, while the other suffers. When you love someone you wouldn't hurt them would you?
