One thing you need to remember is this, you didn't get into this by yourself. He knew that he was married when he started seeing you too. You are correct that two wrongs don't make a right. I have to ask why aren't you interested in any of the single men at the office? I really don't feel that an "office romance" is good for the office. Just when you think no one else is watching, everyone is watching and they are talking too. So, if you have any girls that you go to lunch with or talk too, expect them to keep coming because they want to hear all the juicy details. I would suggest that you end this affair. If not it is very possible that his wife can find out or even that he is fooling around with some other women at the office too. Please don't fall for your the only one because and I've never felt this way about anyone lines. If that was the case then why is he married? We as strong women need to say hey look, I'm nobodies mattress and I am better than the occassional lunch dates and late night booty calls. I want more for myself and I deserve better than this. Hold your head up strong and say no and move on.
