my very first boyfriend ever cheated on me . when i found out i was so mad . well , it is good that you did not marry him . i had a husband who cheated . oh wow . yeah , i ca n't even imagine if i had married him . i 'm glad he showed his true colors early on . i never had to see him again after that . consider yourself very luck . a leopard never change his strips .
The cause that triggered the feeling of anger is infidelity/being cheated on by a romantic partner.
