Let me start off with a story that's pretty easy to tell

Boy Meets Girl
Boy and girl talk
Boy and girl become friends
Girl is already dating someone but it's fine
Girl gets heartbroken
Boy sticks by her and cheers her up
Girl is thankful for support
Boy develops crush
Boy is confused, he has feelings but doesn't want to hurt the friendship
Boy finally decides to tell girl how he feels
Girl responds with "I like you but not like that"
Boy, naturally hurt, decides to stay around, thinking he'll have a chance with her.
Girl dates another guy.. gets heartbroken
Boy plays crying shoulder again
The cycle repeats himself
Boy finally gives up on girl and moves on.
Boy Meets another girl, Girl he had crush on realizes that he would've been husband material had she seen it
Boy and girl never speak, wondering what would've been.

So ladies take a small lesson from this story
If you're looking for someone to appreciate all your glory
If you want someone to appreciate the happiness in your space
most of the time, what you're looking for
is right in front of your face.
