I have long years relation with a married lady in all sense.she has a family friend and the other lady insisting my g/f to have wrong relation with her husband.also that guy proposed my g/f.that guy is a very good friend of my g/f's hubby too.my g/f refused his proposal to him and his wife.
Now the problem is that she cannot tell this matter to her hubby and so she is to go out with them for movies and all with the family.I am totally confused and don't know what to do .she is scared to tell her hubby thios matter and forced to join them whenever they want to go out with family.

I'm confused too! Where are you from? Here in the states, where I am, having more than one spouse is illegal. I'm totally lost about who is with who in you question. You mention your girlfriend. And then her hubby-husband?
The wife should be able to communicate with her husband. If her husband's friend is behaving inappropriately, her husband should know so he can talk to his friend. Although honestly, if I were in his shoes, I don't know how long a friendship would continue with a man who was proposing to my wife...

I agree with the above. Also, if you are involved with a married woman where having more than one spouse is illegal, I would put the brakes on it. She is married. It doesn't matter how much she hates her husband or her husband's friend or her husband's friend's wife (phew) she is still MARRIED. Get away from this mess as fast as you can. You shouldn't be involved in it.
