How do you tell a girl you love her if you are not able to speak before her with courage?

well theres no need ot be feel shy or out of courage u need to just stand up in front of her or take her out and then tel her how u feel she might feel the same way but u r not goin 2 find out if u cant tell her just try if u cant then try again another time but dont give up on your love for her not just yet anyway .
