I'm in love with my cousin
What do you mean when you say you love your cousin?
It's platonic, of course. I love her as a cousin. I definitely don't love her romantically because that would be sick.
For a minute I thought you were practicing incest which would have been wrong and disgusting. well, I'm glad you have a good relationship with your cousin. A loving family relationship is always a good thing because family will always help you when you are in need.
I'm glad you see it that way.
That is the only way that it should be seen. It is not okay to go the incest route.
