So my crush (Caleb) is in my 5th period, math. I told him i liked him through email and he said he liked my back. Sometimes I catch him staring at me and i think it's creepy. Sometimes I talk to him after class and he stares at me. What do I do? Should I ask him out? And why do i feel the urge to touch him because he touched me at least 2 or more times already! (Shoulder, Finger, Hand, etc.)
