Stuck in a Friend zone?

There is a Girl that I really like and we are best friends. I want to ask her out but I'm she says no it will ruin out relationship as friends. I believe she show sting signs of her like we such as: My headphones were around my neck and she pull me towards her and was touching them and we all ways go for skates together. Should I ask her out or just stay friends also what should say too ask her out and what will I say if she says no?

*** I know how that is. I been trying to prevent people from loosing friends.
You never know how someone else is going to respond.

- When you think time is right, ask her out in person
- Explain how you feel in simple terms. Do not get too personal.
-If you go too much in depth, it might scare her.
-Remember: no pressure, give space, be real, be simple, think about what you know already.

- If it is "no"
-Tell her you understand. I Hope we still can be friends. I value our "friendship." (in your own words and based on your friendship-add your feelings about "the good times" you shared.)
-Sometimes "friendship" is better than "no friendship."

-Sometimes, as life goes on, friendships grow strong, and Heart becomes aware. She might feel love for you, later as weeks, months, or even years past.
