I don’t think they’ll divorce for multiple reasons: the codependency issues, inability to be responsible adults, inability to plan. They are terrible for each other but also can’t function without each other. They can’t seem to competently run one house together, I don’t foresee them splitting up and each having to run their own houses. The only way they’d meet new partners would likely be the insane super fans that stalk them. But finding those new partners wow ups be work, and we all know how they feel about work and effort.
