Panchayat decisions are not binding on anybody. No one can be compelled to attend a Panchayat meeting. Their decisions are only advisory in nature at the best.
As regards RCR, have you filed a petition in a court? I think you only wrote to her direct and she replied. Again did she reply in writing or only told you?
If you want her to elaborate, you will have to file an RCR petition in a court of law. If she replies and is summoned to the court, your lawyer can ask her what she meant by “adequate love and respect”. Well in court she may give some other reason. In any case RCR is not enforceable. At best it can only be a prelude to a divorce petition
