I will try to make it as short as possible.There is a girl I like in my class,we talk to each other almost everytime since I made my 1st move which was like 3 weeks ago.I want to take the next step and ask her for her number but the problem is that we are always surronded by other people,mostly girls.Also she always come to class with her best friend.I don't wanna risk asking for her number when we are not alone as it will be awkward for both of us(or at least for me) and if she refused to give it to me,it will make things even worse as I will embarrass myself in front of the other girls too and not just her.Any tips ? Btw,I found her facebook but I don't want to add her as she might think I'm a cowrd.
