Seeking Islamic Advice on a Tricky Marriage Situation

Assalamu Alaikum, I'm hoping to get some Islamic guidance about a marriage situation I'm facing. I'm from India, and she's from the UK. For about a year, we saw each other around because our workplaces were close-she’d sometimes come to my place, and I’d occasionally go to hers for food, but it was all just casual interactions without any real conversations. Then, a few months ago, we bumped into each other outside work and actually talked for the first time. We clicked really well and started meeting up more after that, slowly developing feelings for each other. Eventually, her sister found out. At first, she was upset and told us to stop meeting, but later she agreed to meet me with her husband. In that meeting, they asked about my intentions, which I understood, but they also kept saying negative things about her in front of me, like she isn’t ready for marriage or can’t do certain things. Honestly, she’s a very kind and caring person, so it felt off hearing them talk like that. They also accused me of only wanting a visa or said they didn’t like my appearance, which I heard from her. Her sister mentioned giving my number to their brother, since he’s the most religious in the family, but she didn’t actually do it. After that, her family moved to another city, but we still wanted to see where things could go, so I travelled there to meet her. That’s when they found out again, and only then did her sister finally give my number to the brother. He started texting and calling me, but instead of a calm chat, he mostly insulted me and called me disrespectful for meeting her. I didn’t react badly to avoid making things worse, so my own brother ended up talking to him. After that, they said we could talk properly after Ramadan and possibly meet again, but since then, nothing has really moved forward. What also worries me is the emotional pressure she’s under. Her sister keeps telling her she’s not attractive and no one would want her, which has really hurt her confidence, especially with past bad experiences affecting her too. From my side, I genuinely like her and intend marriage in a halal way, but her family seems strongly against me for reasons that feel unfair. So my question is: Islamically, if two people want to marry but the family objects over things like appearance, visa assumptions, or cultural differences, what’s the right way to handle it? And what should I do in this situation to approach it properly according to Islam?
