I have been talking to a girl in my college course a lot recently. We have really started to bond more. At any point in class, she will either cuddle up to me in the auditorium or I find my arm around her without even realizing it. I find that she likes to hug me and we've started showing up early to class so we can talk alone. I have been hurt in the past and I know she has too because she has confided in me, so I think we're both a little unsure of what to do. I just don't want to take a risk if she may not be interested. Any advice helps, or tips on maybe flirting to find out if she is interested. Thanks!
