need opinion (please no hate)

I'm 15, and recently have been in a relationship with a guy who just turned 18. He is a senior, so still in high school. I'm aware that this is illegal. He has a lot to lose from being in a relationship with me: can't be in Air Force, could be put on sex offenders list, etc... but I'm in love with him, as he is with me. He said he's willing to risk all that because he's never felt this way about anyone before. My parents are fine with it, they like him. His parents are kinda worried if I ever got mad at him I could pretty much ruin his life (which is something I'd never do, but I can see where they're coming from) Everyone I have asked about this has basically said that it is wrong and I should end it. Just looking for some advice, without judgement. Please let me know what you think, and ask questions if it doesn't make sense. Thank you
