Ruth and Naomi were poor. So Ruth went out to pick up the grain which the reapers let fall at their work. The field into which she went belonged to a rich man named Boaz. He was pleased with Ruth, and let her eat and drink with the reapers. He told her never to go anywhere else, but always to come to his field, and he made the reapers let fall some grain on purpose for her. So when she came home to Naomi at night, she had a very large bundle. Ruth went to that field all through the harvest. Afterward she became the wife of Boaz.

So you see Ruth did not lose anything by staying with Naomi.
