I'm pretty new to this so excuse if I've been posting too much lately but I'm an anxious person. Anyhow, I have a pretty good looking GF and recently some guy who is a customer from her job somehow found her on Facebook and messaged her. She told me about it and she was quite amused. I kind of played it off and said "ha that's funny, guess you got a new fan I don't blame him" . That sort of thing. At first I was cool. Ahis first message was about work but then the next message was "sorry to message you this way, hopefully your BF isn't mad"

This is where I started feeling awkward.

She told me about it and asked how she should reply and asked for my opinion .. I was frozen because I wasn't sure if I should get mad or continue to act like I don't care. I mean... should I be mad? Part of me feels like she's also gauging my reaction.

So... how do you guys deal with this in the best possible manner? It's one thing to make small talk but the guy brought me up... which clearly indicates that he has a greater motive. At first I thought he was just some lonely weird customer from her job (who looks up someone randomly and messages them like that.. seems a bit stalkerish . So I thought it was just funny but now my guard is up a little.
