Husband is bipolar

Hi. I was speaking to my mother in law and she asked if my hubby ever mentioned the possibility of him being bipolar. A light went on in my mind as she was describing what his highs and lows might look like. He’s talked about his sisters bipolar disorder and also how he doesn’t like labels. It didn’t occur to me to see him as bipolar but it makes sense. How do you support and deal with a bipolar spouse? Please offer real advice other than go get a therapist. I want our daily lives to be happier and healthier and he would never take pills for it so don’t recommend that thanks.
