I need your advice here please please. Should I text her this?

Texting someone to ask them out is really lame, i wouldnt do that, just get the courage up and talk to her face to face. The key with this sort of thing is to not fear rejection. If she likes you it will be hard to screw it up, if she doessnt like you it will be hard to make it work. Just do whatever you think is right and dont worry about it too much.
