I read here and oh I guess most everywhere of so many "clinging vines"
but honestly, what if she doesn't love you?
What if her feelings are as deep as yours but only for another or perhaps for no one?
How is it that you can't see or that you think your life is suddenly over?
Are you being selfish as you continue to pursue even though she's explained?
"Look you're a great guy, I like you, you're just not the guy for me!"
I think all of us have heard that at least "once" in our life
but not all of us, unlike you, emphatically refused to let go
Try putting yourself in the other persons place and ask yourself,
"How would I feel if that were me" and you'll never go wrong
Try it, you have nothing to lose......
