Achievable??

I am a caretaker for an elderly family member (mother) plus I am juggling a relationship in which my partner feels slighted and resentful that we aren’t able to spend much time together due to me taking care of My family member 24/7, and also due to Covid. My partner doesn’t understand or cares not to try. well they say that they understand that my family member comes and the pandemic limited interactions but they often express there unhappiness with the situation. Should I breakup with them because I believe that an achievable successful, prosperous relationship can happen still in the dynamic , and they’re unsure of it? I give up my moments of solitude and free time which may vary from a half an hour to an hour each day to see them, but they feel it isn’t enough and are feeling unwanted and unsettled. Should I just not date anyone due to my situation, until it improves? Everyone that I’ve ever dated has had a problem with it. Maybe they just weren’t right for me? Can a successful relationship be achieved while being a caregiver?
