Premanand Maharaj Ji
My partner cheated on me or betrayed my trust. What should I do?
Forgive, pray, and increase your naam jap
Even if someone commits the greatest offence against you, try to forgive them and do not be angry with them. Pray to Bhagwan to purify their understanding. Increasing bhajan (devotion) is how you become patient and serious enough to forgive.
And pray to Bhagwan: make this person's understanding pure.
