If you tell her.. just think. At least you cant look back and say "what if?" You had the courage to tell her how you felt and that takes guts. If she feels the same way.. GREAT! If she doesn't, you can still move on knowing that you let her know and she is aware of it. Lets say you dont tell her? She might never know, she might even feel the same way, and if she doesnt, theres plenty of fish in the sea but beware, there are also sharks.
