Alright I don't usually ask questions here but I need to make a decision.

Yesterday at a live music event I chatted with a girl, and after 30 minutes or so the people she was with (one of them drove) had to suddenly leave so she had to leave with them. I didn't get a number or anything yet but I was really enjoying the conversation.

On the FB-page of the event I found her profile, and I'm thinking of adding her and sending her a message, but I'm not sure if that would come of as stalker-ish/too invested. what do you think?

Edit: went for it, she's coming over tomorrow
