The security guard at my job gave me a pack of Toblerone chocolates today. He's here overnight and I see him everyday when I come in before he goes home. A really nice guy, and now I don't know when to bring up the fact that I have a boyfriend.

Just tell him a funny story and go "so this one time my boyfriend and I..." and you might see the light leave his eyes, but it won't be confrontational.
