Help me write a painful paragraph telling my boyfriend that “ I don’t wanna talk with you because I’ll end up making decisions in which I might regret

I'm sorry, but I can't continue talking with you. Every time we have a conversation, I end up making decisions that I regret later. I care about you, but I need to prioritize my own well-being and mental health. Being in contact with you only leads to confusion and pain for me. It's best for both of us if we don't communicate anymore.
