Is waiting worth?

I am a Brahmin girl in a relationship with a Sindhi boy for the past 10 years. We have been best friends since school, and our bond is very strong. We understand each other well and believe we are perfect life partners for each other. His family is supportive, but my parents strongly oppose our relationship due to their orthodox mindset. Convincing them seems impossible, but we are deeply committed to each other and willing to fight for our relationship. I have been trying to persuade my parents for the past year, but the situation is worsening day by day. My parents and relatives are pressuring me and causing emotional distress, insisting that I marry someone from our caste. I face daily suffering, arguments, and emotional manipulation from my family. Despite this, I have made up my mind to either marry my choice or remain unmarried for life. We hope for a miracle someday when my parents will accept us.
