He has trauma
Perhaps your partner has displayed some alarming behavior. He’s thrown tantrums. He’s made threats against his own life. He disappears for days on end. He drinks a lot. You say, “He has trauma.” If that is true, I am very sorry for him. I am truly sorry that he lives with that darkness. And now that I’ve said that, I must also say: you can’t be his therapist. A relationship must consist of two individuals who are healed and whole before coming together. That’s the only way it will work.
