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

well you dont work together now so why not tell him your gay , and ask if he is too  - the worst response will be no response at all and he stops messaging you , if your ok with that risk then just tell him  - every other reply will be better , even if its just to say hes not gay but happy top be friends , but theirs always that chance he feels the same

We still have mutual work friends and he's also in contact with them too. So, if he tells other people about it, it may risk and ruin my life and especially career.

oh yeah that defiantly complicates things , hate to say it but dont take risks ,, i dont know where your from so i dont know how be found as gay could effect your life - as you say you have mutual work friends , dont risk you livelihood and income for a maybe......sorry i cant be more positive , you may well have to wait for him to bring up the subject

Normally, we trust each other and give little secrets or details about our lives. But we keep them for ourselves and don't tell anyone else. This thing... This thing is different. Also, I think i have some clues to make steps. Like sending good morning message every day isnt something we do for friends haha . So, when i see a little light, I cannot just cut it off ((
