While I agree that the whole blowing kisses thing is most definitely over the top and pretty weird, coworkers making comments on how close they are might not always be the most reliable source of information. I have a very close guy friend at work, we knew each other before we started working together and I helped him out with a job here so we have friendship history. We hang out on our breaks and at lunch (along with our other two friends here usually). People made comments asking if we were dating just based on the fact that we hung out/talked all the time. Our work leaves us with a lot of downtime so obviously we kill that time by cracking jokes and making conversation. I don't have very many friends here so I hang with him and a few other people all the time. My other friend that worked here had coworkers comment about her hanging around with her close guy work friend as well, again just based on the fact that they hung out all the time. Working in a dull office 40 hours a week we are of course going spend our spare time chilling with each other. Just keep that in mind, office folk like to gossip and it isn't always accurate. Though based on the fact that your wife admitted to having a crush your situation could very well be more complicated/different. Just wanted to open insight to that as well.
