My sister she is 40 years old beautiful works out to stay in shape has a high position at a coporate office she also cooks cleans her house and is loyal and loves her husband very much. My 43 brother in law he is a jerk not only does he have a strong aggresive with anger issues he cheated on my sister with a this young 20 year old woman who is only into him for the money. Now lets be real her no woman in her 20s wants a 43 year old man unless she's after the money. My brother in law cheated on my sister it is not fair the things he is doing to her. Why are man like this?
