Is it okay if I'm in love with my married co-worker? I'm also married.
What would you expect someone to tell you about being in love with a married man?
I want you to express your opinion on this, I know you want to jump in saying, "how could that be? This can't go well!"
It's understandable that you are attracted to your co-worker. However, you should not feel inclined to act on that attraction. Instead, you should focus on being loyal to your own marriage and working to improve it.
You think I'm nuts and you don't care.
I think you are acting as any normal human being would with affectionate feelings for others. Keep your work life professional and leave the romance at home, this will save you a lot of drama and heartache.
