Nita, I hope your situation either greatly improves, or that you're able to disentangle yourself from it and feel more centered and more like yourself. My heart goes out to you.
There's a recent trend called "Living Apart Together" where couples are living in duplexes next door (or nearby), but not in the same space together... Im not sure about the particulars of your situation, but that might extend you both the space and grace you need to remember why you want to be together? (Just an idea from left field over here).
Thank you for reading!
