Should I (31F) let go of 2 years long relationship?

I(31F) have been ina relationship from 2023. told my parents within 8 months of being in relationship. Whereas he told his parents in 2025 March. My parents were onboard with the relationship in a month. But his parents aren't. It's been 5 months since we told them. They didn't get downa bit. His parents are rigid and conservative. And my biological clock is ticking too. And my boyfriend doesn't have a timeline on how long he wants to wait for their approval. Whenl ask he says he doesnt know. When I ask him about his plan b, still no response. And he says people wait 4-5 year's for parents approval and you aren't even able to wait for 6 months. His dismissal hurt me deeply. And want to let go. But I'm not sure if l should. My heart is breaking apart.
