Asking Eric: My daughter moved in with me but still pays half her boyfriend’s rent

A daughter has moved back into her mother's home without paying any household expenses. Despite living there for free, she continues to allocate a significant portion of her income to pay half of her boyfriend's rent for an apartment she no longer inhabits. Consequently, she cannot afford essential personal costs, including health insurance or a car. This financial arrangement has led the mother to seek advice from R. Eric Thomas regarding the situation.
