The last thing to remember is that you definitely shouldn’t vocalize whose side you take if you do in fact take a side. Just stay out of it because they’re already making your life difficult enough.
It’s such a struggle to deal with this because it feels like you’re being pulled in half. And when it happens to multiple people in your friend group, you just don’t know what to do. But ahh, such is life. You might not know it, but you’ve probably done the same to someone at some point, and life moves on so you have to as well. Good luck!
