Offering what commentary I can:
Always an option, though you have already mentioned what negative long-term consequences that would likely have. Thus this is likely a last resort for now.
WriterAlexis Negotiate positions to gradually increase my freedom.
It would be a solid course of action if your parents were willing to be reasonable. That doesn't seem to be the case based on your description but if you think you can change their mind it might be worth a try. If you do, negotiations usually work better if you have some leverage, so you will probably need either something to offer them or a threat they will take seriously (or both).
WriterAlexis Use a tactical thermonuclear weapon that recently fell into my lap.
I wonder which option you favor, no way to tell at all 🤣 . More sereously, I can't offer much commentary without at least some idea of what you are talking about but I am assuming if you're describing it as a nuke it would cause significant collateral damage if deployed. It might be better to use it as a threat to force negotiation, though to be effective the threat needs to be credible which means you would need to convince your parents you are willing to use it (whether that is true or not).
sidenote: you have done a pretty good job building up suspense around this one. If nothing else, you might have a career in writing serialized television.
As for option 4, you can't help what you're attracted to. It also isn't necessary to agree 100% with someone to start a relationship but based on your (admittedly short) description, it doesn't sound like he would be the kind of person to compromise, and going that route would probably put you in a vulnerable position with someone who might be likely to exploit that. Sounds like a pretty high-risk/low-reward strategy but it could be one you can explore without committing for a while.
