He was not toying with her, this is the life he lives, this is how he was before he met her, his close friends know he is financially well off and if he doesnt want to disclose this because trust me if she did she would have stayed, its his business. He knows what he is doing and has a right to do it, look at it this way, if she knew he had money should would put up with the frugal ways of this man, why? because not only does she have hope that he will change, but she has security. Now who is the cruel person in this situation? The woman, and it is usually the way it goes in life in relationships.
I do not think he is toying with her, he is just living the way he lives naturally and he has a right to do so, and if she doesnt like it she has a right to leave just like she did. I am not going to sit here and clown you like others and say you are caping, but the way I see it I honestly act frugal in general and the same way all the time especially around girls so I see nothing wrong with what he is doing. At the end of the day a man is entitled to act and deal with his financial anyway he wants if a woman doesnt appreciate it she can leave, and how do you know he is toying with her? He may well be naturally like this, I know of people that have 8 digit accounts and live frugal, as a matter of fact the amount of millionaires who live in a house valued at under 300k is astronomical, also the car that was purchased most by millionaires was the new Hyundia genesis, look at billionaire Zuckerburgs little modest home, its all up to personal choices and preferences.
