Aw, hon, I'm pretty sure no one wants to yell at you.
But... you do know the popular definition of insanity?
It's doing the same thing over and over, and expecting a different result.
Unless the people in your life suddenly become not themselves, it will be the same. Things will be ok for a while, then they won't be ok, then there will be tension and fighting, then there will be a breakup.
I gently suggest don't rinse and repeat.
(People can change and become different, find ways to deal with their stuff. But it's hard and takes commitment and time.)
