I'm faking my marriage
Why would you fake a marriage?
For one, my parents do not like the idea of an interracial relationship with a white American.
I'm sorry your parents think that way. You shouldn't keep lying to them though because they will find out sooner or later. It is best to be honest with them and if they can't respect you then you might need to distance yourself from them.
I feel as if I have to lie to them and be in a fake marriage in order for them to accept me and I hate being alone.
It is bad to lie to others, but you should really try and be honest with them. You don't want to be in a fake marriage just to please them, you need to be happy too.
