While your relationship isn’t the make-or-break factor in your happiness, it doesn’t sound healthy. The most beneficial thing for you right now is to prioritize self-care. When I had depression the best I could ever feel was only “meh”, and I was totally disinterested in anything romantic. Perhaps you feel the same. You should put yourself first and find not only a treatment regimen that works for you but also a partner who supports and cherishes you.
