In theory, it shouldn’t matter what anyone thinks. But in practice? If you need to make a living, your digital drama could cost you job offers and promotions, because recruiters and prospective employers do look at your personal social media. So control what your audience sees, and don’t put anything in public view that you don’t want your future boss to see.
You don’t know what the future will hold and you can be committed to your relationship and also act in your own enlightened best interests. Honor your vows, hope for the best, work with whatever good is there, and seek the help of a professional counselor. But don’t be naive and surrender your financial power to a narcissist. Make a dual commitment to your “futureself” and stay open to however that will manifest.
