No guts to propose. I know that she will start crying if I propose her, so I don't propose her. I can't control sending messages in whatsapp as a friend. Even if I propose and she says yes, I can't marry her as her caste is different [Mod edit: Meaning that her family would be against her getting married to you]. How do I deal with this situation?
