I'm still wondering which is the best way in my love journey

I'm still wondering which is the best way and what is the choice for in love journey. Should I take a risk to tell her I Love Her and the result might be either success or I lost a friend. It's very difficult for me to make the decision. If I don't try then I will never know the result. And if I keep on thinking here, I'm wasting my time and maybe will miss up the timing. What should I do?
