My husband having extra marital affair since more than two years

Recently I came know that my husband is again having affair. I am married for twenty three years with a grown up Kid. My husband is not loyal to me and he had extra marital affairs, two times after marriage. He is working outstation and had come to home since last two years. And as a proof, this time I am having call recordings where he is having romantic talks with other lady and showing physical intimacy towards her. That lady is married with a kid and when I talked to her husband regarding this, he said - my wife is not like this even after hearing the call recordings. But when other relatives heard, they said they said They both are highly greedy. And had offered to built the house on their plot where my husband can live with his mother. And in return my husband has to build the house for them in half of their plot but they had not registered the half of the plot in my husband's name. And my husband had purchased one more land in that area but that is registered in that lady's name. In my early marriage days, his mother torchured me a lot and he and his mother had beated me even number of times. But due to social boundings, I didn't stepped out of this marriage. He is badmouthing, ill-talks and talks rudely with me He is also not giving any money even for monthly expense.
