It's a simple decision. Do you want to be with her in 2 years time? If no stop today. Stop all communication. If you want to be with her its 5,000 a week or nothing. Let her decide. Do you want 5,000 or nothing? You have the power not her. If she argues finish it today. Just common sense. Nothing else to think about.
I don't know why guys fall for all the lies.
