What do you think about me falling in love with my cousin and letting her know?
Do you know why you fell in love with her?
Because I find her attractive, because she's stunning
You shouldn't be having a romantic relationship with a relative that close. If you are having feelings for her like that you might want to try and distance yourself.
It was my choice.
It is your choice, so you should make a wiser choice and not jeopardize your family relationship. It is inappropriate to have romantic feelings for your relative.
