that's the best move i guess.
sometimes you need to remove yourself from the situation in order to not get hurt again. in order to avoid building anger and jealousy.
no one owes you anything, esp. not when it hinders their happiness. if you're holding the solution, use it. it doesn't mean you become happy, but peace, you get peace. there's nothing else you can do about it, and that's the only way you can go around it.
they might not even know how much their actions affect you because they don't even know its impact on you. so maybe the best course of action is to un-know its impact on you as well.
