Funny, but I’ve gotten the same feeling. It would be hilarious if they got divorced now. Why do they still need to stay together?
Money.
Legacy.
There’s no reason for them to separate.
Lots of legal stuff potentially coming up - if married, they have “spousal privilege” (see link). If they divorce, that spousal privilege ends. They will never divorce.

Who knows? Maybe so they won't testify against each other in court.
They need to stay together because of all that money and because they need to be united behind Chelsea as she is slipped into the Dem political machine. That’s purposely in passive voice.
Also, they are both old, which is not a great time to make a huge change in your home life. They knew each other when, they each know where the bodies are buried. Divorced elderly don’t live as long or as well.
From my point of view, it would be great to see them part with animosity. Together, they remain a threat to freedom and the republic.
Money and dirt. They know exactly what they and those who conspired with them have done. They have been a very powerful crime team. It is to dangerous for either to leave the other at this point not only from the stand point of the damage they could do to each other but from the fear of those powerful people that they have conspired with. Life could become every short and painful.
