When somebody loves someone, but they don't love them back, whether there heterosexual or homosexual. Often times the person in love is miserable and just longs to have the other person feel the same way and to be near them. To just look in their eyes and feel that there is someone who cares. Someone who loves you with their heart, not thinking so much and just...to hold them forever. But the person doesn't feel the same way. And it's like they are ripping out the one in loves heart. So people are too afraid to tell the person that they feel this way...and the person never knows.
Girl walks up to a boy and pulls him a side.
Girl: "There's been something I've been wanting to say to you. It's hard for me to say it, but here it goes. I...I'm in love with you."
Boy: "What? Listen, you're a great friend and everything, but I'm sorry. I just don't feel the same way."
The girl nods and walks away with tears streaming down her face.
