Because of todays Women mentality its difficult to manage both ends and keepup with Parents and Wife. you have to devote to one side. As you are married your duty towards your family is more than your Parents.
She can file Dowry case even you have not taken or demanded any dowry, even Domestic violence case. if she is talking terms, take hidden voice recorder, and talk to her about no dowry demand or no domestic violence etc. it will help you somewhat to justify in front of court or Police if she file case.
Also you can write to Police / SP about she left you her own and now threatening you with False dv/dowry case etc.
if she dont allow you to meet your child, file a petition in court for visitation rights.
