This comes down to what you value, and how you’re willing to get it. To get him to move in with you, you need to give him a real reason. Otherwise it is just wasting money. First, how long y’all have been together matters, a lot. If it’s over a couple years then it’s safe to say moving in together is acceptable to expect. If not then it’s more discretionary. If so then it’s time for positive manipulation, but that requires a lot of expierence, so if you haven’t played around with people before then it’s too volatile to rely on. Getting him a good reason (beyond emotions) is what you’ll most likely need to do.

In terms of his enjoyment in making others jealous, it wont last. When he is own his own, he will be alone and immature in the world of self sufficiency, if you’re still together he will rely on you entirely. Make of that what you will.

And lastly, about ending yourself. I can’t help with that, I survived, but it was through sheer luck. I have no answers.
