Husband is struggling

My husband recently told me he was struggling personally and needed some space. I found this super frightening to hear.

My model:
C: Husband says he is struggling
T: I am not keeping him happy. He is going to leave me.
F: Fear
A: Ruminate on this, try to fix things, be disingenuous by not being who I truly am but instead trying to keep him happy
R: I don’t show up as my true self, I make myself unhappy

Can you help me get out of this unhelpful thought loop?
