My husband involved in illegal activities..I want divorce..please help.

Sir, my husband is a businessman and there occurred a loss in his business and he said his friend will support him financially and he left us before 5 months. Till now he didn’t comeback and he is saying that the work has to be completed through bank and it will complete today or tomorrow.the same story is repeating from 6 months. He is sending some money through online for household and grocery and kid’s school fees. He is doing something illegally..I don’t know know what he is doing exactly but I know they got some bank loans by showing somebody’s properties and bribing managers.but now the situation was different. The persons who gave amount to my husband and asking money..my husband switched off his mobile and changed his number and asking me to tell them that he is not available and I don’t know about him. Sir, I am not intersted in this marriage any more. I am vexed and I am afraid about my kid’s future. My husband interests are only about money but not about our family.. I want to live separately and I want to take care of my kid. Let him do his business with his crores.
