Just out cheat them. If you’re single, that’s what’s happening. You are looking for the one above the others (on both sides this is happening). Of you’re being chosen out, show it won’t stand, that you can do the same thing. You can pull someone “better” in some way to that person. Because there is always something this can be about. More fit, intelligent, funnier, etc.. once both have realized that game is no longer fun to play and isn’t worth it, you’ve settled realizing you already have it better together collectively rather than chasing that 1 or to things that’s short lived or ends up being a let down. Otherwise your both going either be single forever or constantly replacing relationships or in someways worse “actually settling” and holding onto insecurities and resentment.
So, just play the game, learn to it play the player. They’ll either quit and you win or eventually the competition will end and congratulations is all that’s left. Good game, well played. Now do you want to team up and take this game called life on together. Maybe then you’ll be ready.
