Mr.Anil Kumar
Your next period is of Jupiter dasa Mercury which is from 3-12-2025 to 10-3-2028. Mercury is signifying 6th and 12th which are the significators of separation. But Mercury is signifying Jupiter lord of 5th and 8th which are 11th (fulfilment of desires) and 2nd (finance) to your wife. So I presumed that the separation would be through her job.
Good Luck
