I got this girl from my class number. First day of class our eyes met four and we just kinda connected instantly. Great looking girl, so since I know we got the same class I waited until I saw her in the next session and I gave her my phone and told her to put her number in my phone. I texted her like 2 days after since I was extremely busy working on stuff. We exchanged about 4 to 5 text each. I messaged her , and she asked me what's up and whatever and told me she was just finish working out and chilling and that was pretty much it. That was like a week ago. I haven't messaged her since. She sent the last message, which basically never needed a respond. Now I want to know how to approach classmates situation with girls. Like I got no clue if she has a bf, I am not looking for a relationship but would you ask if she is single before letting her know to come chill with you when both of us are free and don't got classes. Or just proceed without knowing if she is single or not. She seems interested for sure, since the interaction wasn't 1 sided. She seems extremely shy as well. Before we enter the class, she was hiding behind a wall. I had to tell her to come in. She seems really submissive as well from just how small interactions. When I texted her my name after I got her number, she was like Yeah, what's up? I told her I just hit her up so she can have my number as well and she was like thank you, seems a bit interested but I kinda want to know where to go from here since she is a classmate
