I know exactly how you feel.
I've had a crush on someone for at least 12-13 months. I KNOW it's love. But it just can't happen. I feel dead inside not knowing I can have her.
The truth is, I have been trying to forget about her for probably 6 months now, but I just can't. Everything I see and hear about her reminds me of the times we have had, that amazing personality of hers, etc...
So I'm sorry to say, I have no idea. But I know that it's the worst feeling in the world, not being able to have the woman you love, and not being able to move one.
Sorry, and best of luck.
