Hi Dasumi,
I don't know where to start, my SO can be alot of work when she makes me become a caregiver and I want to have a romantic relationship not a care giving one.
Good observation
She is shifting responsibility on you and then you are going to take the blame for everything that is wrong . And yes, becoming a caretaker is not doing much for romance.
Study the LESSONS. There are techniques that allow you to shift responsibility back to her. I won't tell you it is easy but with a bit of planning, possibly preparation discussion here on the board you may well be able to put a stop to this playing child of hers. Read up on boundaries. Again it takes some planning and thinking through so don't rush into it.
Becoming isolated is somewhat normal here. But so are then efforts to reach out again. Try to protect the few tenuous links you are having. Try to create new ones. Often isolation is a sign of exhaustion and depression. Consider reaching out to a T for yourself.
