Not gonna happen.
But here's a tricky ploy one can use if they have enough money to do any the expensive part of this ploy (which is moving): move to a different house, to make sure your ex doesn't notice that it's you. Join tinder under a different account, and claim yourself as a different identity (not gender identity). Use any stock image in the middle of the google image search, not the beginning or the end due to it being obvious it's a stock image if a search is done with reverse search or normal search if the image is at the beginning or the end. Try your best to match your ex with the undercover profile of yours. Message her and some shit, and make sure to act like what your ex would call her type (I'm assuming you're a male, sorry if I'm wrong) to make her not reject you. Send the address of your new home and your number to make sure she meets up with you. They might come in eventually, and try to do anything you can to get your ex back. Try to make her revive her relationship with you. You can have sex with your ex now and do all that shit you do but with your ex who might now be your wife soon if the ploy even works!
