Suggestion required

Respected Sir/mam, I have been married since 3 years. Last year July i got to know that my husband was having an affair with his colleague from the very next month of our marriage. Last October he broke-up with her after lots of drama from the girl's side. ANd took the decision to do navy job. I asked my parents for financial help. They gave the entire course money. Now the condition is that i have been working from last 9 months since he isn't working. And he is staying with his parents in his village leaving me alone here in kolkata. His mom is a witch, she usually brain washes him to remarry & divorce me. And he is totally a mama's boy. Since one month he has not returned from his village & neither msgs or calls me. I did so many things for him, but he forgot everything. I do not want to divorce him. But he is not at all concerned about me . Pls suggest what legal steps can be taken. Regards Saanjh
