If you mean between you and your wife combined, then you're misleading people and a narcissist. So if you have a wife then you must have 2 million combined in order to have 1 million (for yourself). Also, if you have debt, that needs to be mentioned at the forefront. Any loan/mortgage is debt.
Now if you asked this question a week ago, I'd have said put 50k on Alabama to win the college basketball title. Boom 500k return a few weeks later. Then slap 1 million of your 1.5 down on a bitcoin etf and put 350k in a lower risk investment or interest savings account that will net you a slow profit. Then pick up a couple side hustles or even quit your job if you don't enjoy it to escape the oppressive designed governmental system/the matrix. If you have an American or Canadian or non eastern European wife, you've obviously made the mistake of entering into a contract that logically does not benefit you.
Everyone makes mistakes, some bigger than others obviously, but proceed accordingly based on the foundation you've put down. A divorce would be financially troubling, not devastating if you don't catastrophize, but again, that's the gamble you've potentially made.
If you have kid/s, make sure to raise them as well as possible because you brought them into the world without their initial consent to that. Too many egregious "parents" out there today and divorce before kid is 18 should be grounds for child abuse but also a toxic marriage that lasts could be abusive to the kid/s. Don't put these vulnerable and precious individuals into an undesirable situation they didn't ask to be in. Anyways I've got to go have a beer or three but I can provide further advice if required. Good luck.
