I’m a college student and I met this girl while studying with a friend. She’s a friend of a friend of a friend, so running into her is tough. I won’t get into the details, but the whole night the group of us was hanging out, she definitely seemed to be into me. She asked me to run her a favor, which I did, and then when I saw her later she was wearing more makeup than before. She even asked me to go skiing with her, but I couldn’t justify a $175 lift ticket at Killington on a whim. She seemed disappointed when I said I couldn’t join her. When we all split up, she definitely looked at me while leaving and I messed up and was shy and didn’t get her number. I’m not super close with everyone there who knew her, so I didn’t want to be that guy. Now my only means of contact are her school email (which everyone has and is not an option) or through Instagram. I feel the ladder is the better option, but I still don’t think it is a good one. Any ideas on how I should get her contact? I do plan on asking her out relatively soon after I talk to her. Thanks any ideas are appreciated!
