Need advice terribly, interfaith relationship (F23, M24) please help!!

Hello all (and I’m sorry if this is in the wrong subreddit),

I (F23) was born an American-Arabic Muslim and met my partner (M24) an Indian Hindu three years ago at a coffee shop in Italy. We instantly hit it off and we are both convinced we are soulmates because the connection is so powerful between us. I truly love him and I believe he loves me too.

Unfortunately, his father (M45) seems to hate me for being Muslim. It’s to the point that no matter what my boyfriend says (that I converted, that I pray, etc), his father does not care for me and refuses to let “a Muslim” marry into his family. I have never met his father for context, and his dad and him are currently in India.

He tried talking to his father a final time about marriage before his father told him that he “ruined [his] own reputation by his own hands, and that [he] gave his relatives a reason to laugh at [his] family.” My boyfriend said there is nothing more he can do, and that the only thing I can do is try and text his father and convince him to let us marry or to at least call me.

I am terrified and don’t know what I can possibly say to convince his father, and I am scared there is nothing I can say that will encourage him to at least let me prove that I am good enough for their son.

For context, his grandma thinks I am beautiful and his mother loves me to death. His father and mother also got a love marriage where my boyfriend’s mother’s family cut her off for marrying his dad because his dad was a gangster at the time and she was higher caste from a good family. His brother is also getting married soon in India, and I have been invited to the wedding to meet his family.

I know most of you will tell me it’s not going to work, but I want to try my best before giving up because I am deeply in love with him and would be absolutely devastated to end this relationship. Please help me! I will do absolutely anything necessary to make this work between us. I understand this his hands are tied because his family’s respect means a lot to him, so please don’t put him down for this.

Please help!!!!!
