The person I love is from a different religion. She thinks it won’t work, her parents wouldn’t approve. What should I do?
This is so much more about risk than it is about her parents (and yours).
Different religion will bring risks and challenges during both of your life together, your children’s life, relationship with neighbors, society, and families.
These risks and challenges are on top of other risks and challenges you’ll face because of personality, conflicting values, economy, faithfulness, and so on.
Religion won’t be the only problem you’ll face, but you’ll wish you don’t have that problem when you have other problems piling up on you. Life isn’t a game where you can reset and replay. Life has serious permanent consequences, especially when you make a big mistake.
Work on improving your attractiveness. Your question is result of tunnel vision, you may feel that you’re on a tight situation, but actually you can make effort to expand your choices.
Besides, if she already feels that it won’t work, that means the only reason left why she’s still into you is because you currently don’t have another choice. But what happens if you do have a choice?
