File RCR, win RCR or lose RCR, wait 1 year file divorce. Best wait and watch approach. No use worry simply. Forget custody of child. If possible adjust with wife for peaceful life. Forget court kacheri. Give complaint on wife that she will do sooooooooocide.
Dont jump now, take one step at a time. Talk to wife, suicide not answer to problems. If tke extreme step, face consequnce. Report to jurisdictin police station now itself that she threaten to commit suside.
