What’s the best and the bare minimum is entirely subjective. Either of you may think you’re a great partner but not be one to the other in important ways. Talk to each other about love languages and communication styles, what you need from the other to feel appreciated WITHOUT attacking each other or making negative assumptions. See how well what you both say is lining up with what you’re doing and if it’s not see if you’re both willing to make those changes.
Well if she’s literally not doing anything for you at all why are you with her? I think your feelings are valid and she shouldn’t automatically be dismissive. At the same time just going “YOU’RE making me lose feelings and YOU’RE not doing anything for me but I can’t name anything I WANT you to do” isn’t a great way to communicate. Again feelings are valid but sitting with it and figuring out how to express it better may help.
