Crook The Straight!

Does love happen between two lovers with opposite sexes only? What about between two lovers with the same sex? Aren't they bound to be together always? Why is it that man can't love man same as a woman can't love a woman? Why do people often think that it is repulsive to love someone with the same as yours? Am I going to doubt them saying, "Love conquers all?" Or should I just sit down and watch how it goes?

How can I tell her I love her if her heart only beats for guys? How can I convince myself that she doesn't care at all? How can someone be unreasonable enough to reject someone like her? How can I make her fall in love with me? How? I don't know how.
