Hard Choice Between Family and Personal Joy

As-salamu alaykum. I'm sharing this for a friend who's stuck in a huge problem and needs to make a life-changing call. I'm all out of advice, and the only thing left might be to get him a Muslim counselor, but I'm not sure he'd be okay with that. So, this brother, a born Muslim in his early 30s, cares deeply for a revert sister around the same age. But his family won't accept him marrying outside their culture or community. They worry society will judge, things will go wrong after marriage, the families won't mix, she might change (like they see in Indian media), her faith isn't real, she won't blend in, and that he'd end up unhappy. He's talked to every family member, tried everything to convince them. Now he's just going through the motions, barely there, and his cheerful self is gone. They flat out told him: if he goes ahead with her, he has to cut off the whole family. I've met the sister – she's truly kind, no bad intentions. She prays, fasts, stays firm in deen, and really hopes the family comes around. But then, this past December, they forced him into an engagement with someone from their circle, even though he kept saying no. When he went home for his yearly visit, everything was set up, saying they'd already promised the other family and can't back out because of reputation. He's been super stressed since, had two panic attacks. He's got three older brothers and two older sisters, but no one listens – they're stuck in their views. His mom passed away years ago. He feels trapped, afraid to go against them because he doesn't want to hurt his father or cause any health problems. Now he's worried about three things: 1. The sister he promised to marry and loves – he wants to make it halal and give her a respected life. As a revert myself, I get how hard it is for her to find someone trustworthy and loyal, especially in our country. 2. The sister his family committed him to. He's soft-hearted and doesn't want to harm her, as she's innocent in all this. He's scared her baddua might ruin his happiness. Plus, her father passed away a month ago, so he's not sure how she'd handle it. 3. Losing his family for good. He loves them like any child, but he's hurt and disappointed they've ignored his needs and happiness. As his friend, I'm really worried about his mental health. I don't know what to do here. Please don't judge this brother – he's honestly a good man who follows the deen. It's a sad reality, but many Indian men, especially from smaller towns, face huge family pressure. They're taught to put themselves last, hold family values, hide feelings, follow tradition, and 'be a man.' If this were my own brother, I'd seek the same help. So I'm just asking for sincere advice from the Ummah, no negativity. Feel free to ask questions. Jazak Allah Khair.
