A lady got involved with a man that is living with another woman, there has been no relationship between them for 2 years. He asked the new woman to marry him. She sent him naughty photos, now the woman that he lives with went onto his phone without his permission and found the fotos and sent them to herself. She is now blackmailing the man to stay with her or else she will send the photos to the new womans kids school, to her work and place them on social media. What can be done from a legal point?
