Fiance has crush on someone else?

I agree with O&S...hell no he better not be 'crushing' on another woman. also hell no to 'work husband/wife'... that's silly af.

that said, it your suspicions appear to be friendly gestures as opposed to something more. I think it's best to talk to him and tell him how you're feeling. I know when I explain to my FH how something makes me feel and why it makes me feel that way, he can be pretty accommodating to my needs!

My advice is to sit and have a conversation about how you feel, in more detail. If you bring up, "Hey (name) I have been having insecure feelings because of (reason)" then I feel like your FH will listen and work out these with you.

I am also an insecure person and have trust issues. My FH knows this very well and I am lucky to have found someone as understanding as him. But he knows that I have these issues and is willing to help me with them. Your FH sounds like he might be willing to do the same!

Yeah I dunno, I get crushes all the time. Doesn't mean I'm gonna cheat on the best thing that's ever happened to me.

ETA: Clarification: I would totes make a move on these people and/or date them if I wasn't in a relationship.

Thank you everyone! You all have been very helpful. It's good to gain perspective. I may just not bring it up again, ride it out, and if it happens to come up again I'll have a more detailed conversation with him about it.
