Can’t process husband’s comment about election

My husband and I support different political candidates in the presidential election. We generally avoid discussing politics for this reason, or maybe I just avoid it. He made a comment today that if I am going to vote for the other candidate that maybe we shouldn’t be living together. He tends to make extreme comments at times to make his point about something, so intellectually I know he isn’t trying to say we should get divorced, but I am really struggling with this comment. I could use some help starting to work in this before my next coaching session.
