also with a guy 10 years younger

, big but though, he is my boss, very influential where i live and married, He has a very strong hold on me, i have now been with him 8 years and our love is really strong.
i'm fine with the situation as it is, but he now wants to leave his wife, and that I cannot do. loads of reasons, main one being that he has a family with her!!! and he says he doesn't love her, but i know he does, in a different way that he does me.
i won't leave a job that support me, so how can i break it off? i do love him.
