Yesterday I found one of the hot girls in our office alone in her room, move in immediately and started a conversation, I caught her while checking her fb, I teased her about telling the boss about this and asked her to add me now so I won't tell, then I flirted a bit ate her cookies and received a ton of IOIs. accidentally it was her last day of work, she quited to pursue her studies for uni, so I wont see her in office again. I asked her for # but she resisted and I didn't insist. but I have her in fb. what should I do now?
