@susanna: I really appreciate your desire to save the marriage and restore peace in your family, inspite of all th e mental torture meted out to you. Hats off to you!!!
Since you are very confident that you will be able to change his mind if you or some wise people talk to him or counsel him, you may try the following steps :
1. Send some elders, relatives or well wishes and ask them to talk it over with him. Also send a message via the elders that you would want to have a conversation with him. Convey that he and your child are most important and nothing else matters for you in your life, and will consider any adjustments that he might suggest. Hope you succeed at this stage and bring him to conversation table. If not,
2. File two petitions, one under section 9 HMA for restitution of conjugal rights and the second under crpc 125 for the maintenance of you and your child. The court will provide you an opportunity for mediation/couselling before going ahead with the rest of the proceedings. Use this second step, only after you are convinced you have failed in the first step. If mediation still failed then I would think there is not much in the marriage. He can not marry until your marriage is judicially dissolved which might take several years.
Please do not try 498a/dv if you have slightest feeling that you want to restore your marriage. This route will only ruin your marital life and will only cause more enmity. Use this route if you want to settle scores with them.
