Two coworkers having an affair

I'm having an affair with a fellow co-worker we're both married are marriages aren't the best! We've known each other for 11 years. We both have had affairs before. Over those 11 years we've talked about our lives. We have a lot in common. We are both married two older people who are about 10 years difference we are both 50 years old. Our children are all grown. One day she pursued me, it would take a long time to explain why! I've always had an attraction for her but always kept my distance. She hit on me really hard one day and asked me for my number, so I gave it to her. It didn't take long for both of us to fall in love and we both didn't expect that to happen! We've been seeing each other for six months and we both want to be with each other for the rest of our lives. I know my marriage is over and she says she not happy in hers marriage. I've always said I would never get mixed up with a married women but it happened. It's been the hardest relationship I've ever had! We both plan on leaving our partners soon so we can be together. But she has this heart that doesn't like hurting people. She has said she loves her husband but not like a wife should and doesn't want to be with him. What I'm afraid of is she's going to be afraid to actually leave him because she doesn't want to hurt him. So does anyone have any advice or experience in this kind of relationship. But I love this woman so much, she's always on my mind and she also says the same thing.
