I love a co-worker and don't know what to do.

Well if the text messages are would be called "elevator talk" which would be like "how are you?" "how's the weather?" type stuff, that does get boring. There does need to be more meaningful conversation regardless of whether it is a friendship or something else. What sort of things do you talk about? Do you get any vibe that something has changed?

My thoughts are probably to keep the status quo. Let him divulge that he is gay and it needs to be beyond a shadow of a doubt and I would like @"CodyH" 's said take some caution. I don't know if it is common for random people to go around outing suspected gay people in your country but if it is a thing be careful. People know no limits. Unless you want to roll the dice that is.
