Look I’m going through the same thing just from a girls perspective, I hint things at him and he doesn’t get the hints. We are both shy and he goes to my school. We don’t really talk to each other at school, but talk on Snapchat. You should just tell her you like her, because I wish the shy guy I’m talking to would say he likes me just straight up rather then beat around the bush. See how she feels, and go from there. How else are you guys supposed to go further if you two don’t say how you feel! And also try to talking to her in person first a little more.
