Should I ask her out or not?

think about how you see yourself, like dont think your unattractive becouse then your just going to be freaking yourself out more, think about what she would like and what you have, calm down, take a breath and just talk to her, you dont have to just talk to her to ask her out, just ask her how her day is and whats shes up too and if the conversation is going well then you can ask her out when you think its right, if she knows you like her and she knows your shy then she will understand and i think that she will appreciate that your going out their and talking to her trying to win her over, i dont think that shes just going to regect you, just be their for her , help her out if she needs any help and be nice to her, sooner or later she will find out how good of an guy you are
