If u realy like this girl then ask her if she likes u back and if she says yes then it well start being some serious then that's when u start 2 buy her things
This is what a friend a friend mine would suggest but me I would say get aquented
Take it slow and become friends though
Try not to humilliate your self show her you are a caring person but don't act to sensitive or she will think your crazy I to know how you feel but don't go hard on your self to be with her don't love be your main goal.
