Suggestions regarding boyfriend left woman but still paying expenses

I am a 34 yr old Christian divorced woman with a 14 yr old child. I was in a relationship with a hindu man who was undergoing divorce. We were supposed to get married as soon as he would get the divorce. We shifted together in a rented house. I shifted to Bangalore for this reason. I was made to leave my Job for this reason. He bore all our expenses, school fees, house rent and all other household expenses.We posed as a married couple in our apartment.He shifted to another city stating its a job transfer in after 3yrs. But continued to pay for the expenses. Same year I too left my job with mutual understanding. Initially he used to visit us every weekend then it reduced.But in a years time he suddenly broke of the relationship and this yr he got his divorce done and married another woman. He is still paying for our expenses I'm worried what will happen if he has to discontinue. I am neither much educated nor wealthy. I am completely dependant on him. What can i do in this case.
