Help... advice needed on what to do about him?

Uhm, if he says you guys keep eachother going, & you're not sure if he feels the same way about you, you might not want to say anything.. Or the outcome will be awkward. & HE'S MARRIED MIJA.. & if he has a family, you shouldn't break it apart.. Just because, you know "Dont leave the one you love for the one you like, because the one you like will leave you for the one they love" Maybe not in the same exact words, but karma really does exist.. & if you ruin his family off of liking him that will be terrible. Just continue to be friends, if him & his wife split, or he says something to imply he no longer wants to be with her, or that he also has feelings for you, than at that moment you can mention how you feel, and ask what he would like to do.. What is best for the both of you. & if you hate your job, find another that you will enjoy, and then resign. Make sure you have one before you quit though.
