Search Results: should i try to go out with him

I know this one girl because of us being in the same scholarship cohort. Before I used to always notice her staring at me and even when I was stare at her back she continued staring until I looked away. With that I was 80% sure she was interested. I didn’t bother talking to her because I was interested in someone else at the time (well for a long time). Recently I thought about trying to talk to her or at least to get to know her more. I have her phone number but that’s only from the group chat for the cohort. I personally thought it’d be better to add her on Snapchat since it’d be more casual but I also feel weird that I would be adding her through search. I’m not really sure how to go about this since I don’t want to come off too strong since I’d love to be friends with her too. Also since I’ve know her I never really talked to her either. We have the same interests and all. I also could very much so be overthinking this too. What are your opinions on this? Never used this site but I would assume I can reply to people so if you have any questions just ask.
