This is what my girlfriend is going through right now in England 12 months after divorcing her Indian husband. Even though we reset the iphone and change icloud he somehow manages to phone spy again within a month. Giveaways include sending messages a few minutes after he hears or reads something offensive, one time two of his friends tracked and followed us to a cinema.
