So I met this girl in my calculus TA tutoring session. It was me, this girl, and two other guys (both gay). We talked and laughed etc while we did our work. The girl even blatantly said "I like you, your so relaxed and whatever". So at the end all four of us were talking, I was gunna ask her number but I didn't want to do it in front of everyone. Then she says "why don't we all exchange numbers so we can help each other". I feel like she was just trying to get my number, am I right? Then today (the first time I've seen her since) I was in the lecture and she walked in and sat on the opposite side by one of her friends. I'm hoping she just didn't see me. Should I text her and maybe say I didn't see her in class, was she there? What do you think? Advice?
