I don't get why your only choices is to help or reject him.
Why not just accept him as he is and tell him it was clearly a misunderstanding and teach him how to be more clear next time?
I don't really get why you'd want a healthier relationship.
The only thing he needs is to learn to let go and do whatever you want. I'm SURE he's capable of removing any threats to your relationship without actually harming or restricting the one he loves. He just need a little guidance.
It's a really short game tho.
(At least if you don't upset him. But he's cute enough, not particularly bad-looking (providing he shaves better) and nice enough that I don't see a reason to do that.)
Overall I like the game.
But I'd like it a whole lot more if I could have given an answer -I- actually would have.
And believe me: It would not be one that improved his mental health.
But if the guy is good-looking and have a personality I like, I don't see why I would reject him either.
Not to mention, if the game was longer then a more cunning person could make him trust them before they made a run for it.
It would be the smart thing to do.
(Assuming you quickly left the country, and ensured that nobody, not even family or friends, knew where you went.
The world is a big place. Even the tenacity of a yandere cannot comb every inch of it in a single lifetime.
Searching a single semi-big city is hard enough; the whole world... that's pretty much impossible. Especially if he's not rich.)
I'd love to see a longer version of it tho.
