There is no legal definition for your question, the merits of the incident with specific circumstances would need to be looked at - take it to a judge and file the case under something like "breakage of heart" or something - then see what answer you get back from the court.
“You are under arrest for breaking someone's heart. You do not have to say anything. But, it may harm your defence if you do not mention when questioned something which you later rely on in court. Anything you do say may be given in evidence.”
