Help!

So my girlfriend lives far away and I've never met her in person :/. I love her with all my hart-, hart but I don't want to be with someone who will never be able to come see me. Her parents r super religious and hate gays and I really don't want to be with someone who keeps me a secret. We fight a lot and never tell Each other anything, we haven't talked much and it hurts me that she never replies. She's so sweet and beautiful but I can't be with her anymore it's making me depressed, but I just can't seem to break up with her, what should I do?
