Need a little advice about a girl?

Alright I work with a woman about 20 years older than me. We have been working together for 2 years now. Its mainly just her and I working alone. She's been married for 18 years. Recently, she asked me to meet her and told me that she has become very attracted to me but doesnt know what to do about it. I feel the same way, but I would never help a married woman cheat. What do I do? How do I act at work now? I cant let things get weird between us. This is a strange situation. HELP!?Need a little advice about a girl?
First be a man. Remember always that the ';real'; man is the one that can say no. Don't become a sex object. The fact that she is married tells you what she wants you for. Give yourself respect. I am sure there are plenty of single women you can date. Think of what you want to be known as and that will be the way you will act at work.Need a little advice about a girl?
tell her that if being in a relationship with you is important to her, she should get a divorce, or separation form her husband.
tell her husband dont do it with her thats sick
