I need some advice

Well during the holiday Muhammad told his uncle about us and seeing if his uncle can talk to his parents and the next day thats what he did. His father got really mad and threatened to find Muhammad a wife in a week but his uncle told him to calm down. And yesterday Muhammad talked to his mom and his mom told him that they r flying here so Muhammad can sign the marriage certificate. So he can marry his friends daughter but she is back in Pakistan. Muhammad wants to marry me but he can't go against his family or the will disown him. His father ryt now is getting all the paperwork for marriage ready for Muhammad to sign. His father doesn't want to speak to him and his mom is still angry. His friends and brother are saying listen to ur parents and get married. I have already converted to Muslim before this started and I do want to still follow their families traditions and culture except the arrange marriage. I really don't know what to do or who I can ask for help.
