Ruling when Husband Abstains from Spending and its Impact on Marital Rights

A woman married a man who has two wives. He refrains from spending on her and providing her with a residence. To avoid divorce, she stayed at a house that she had bought before marrying him, and provided for herself as well. Does he have the right to have an intercourse with her, although he provides her with neither food, drink, clothes, treatment nor a place to stay?

A man has married a second wife and deprived the first from maintenance and overnight stay. He spent most of his time and wealth on his second wife.
