I really want to, but I don't think I'm even suppose to know about her and her boyfriend.
I only found out by a series of coincidences and bad timing. I had reactivated my Facebook account to see what I've been missing and I was going to send her a friend request, only to see her boyfriend had commented a bunch of flirty emojis on her profile pic. Her relationship status is private, but I saw his profile and his said that he's in a relationship with her and that's how I found out.
If I hadn't reactivated my Facebook account and creeped on their profiles, I wouldn't even know about them together right now. I don't want to talk to her about it and reveal that I've been Facebook creeping.
