Maintenance

No benefit of filing first case.

After filing case court will decide the maintainance.

Yes under IT act 2000 such evidence had value if verified by SMS.

If u like my suggestion then give THANK on my profile.

Whoever files the case must prove their allegations to get divorce.court won't straightaway grant maintenance as asked by your wife.it will look into variety of factors before deciding the maintenance amount.whatever call recordings you produce will be anyhow sent to a forensic expert

In order to avoid future calamity, all meeting options should be exhausted by husband.

If you approach court at first instance then you will be giving option to wife to open can of worms and it will be disatrous.

What you claim to have as proof may or mayn't stand in the court of law. There will be enough law acts that will be thrown at you even before submitting evidence.

Restrain. Involve elders. Be fair. Maintain coordial. Let time heal the process. If all fails, you need to be separated even before you can apply Divorce. Lack of respose from wife may only allow RCR option to you. But not divorce. Unless your records prove otherwise
