8. Your Japanese girlfriend wants to spend more time alone
She finds reasons to be alone or hang out with her friends to avoid being with you. When she says, “Stay home and relax” or “Get some rest,” it might seem like she is worried about you; on the other hand, it might just as well be an excuse to not be with you. The more often she makes up an excuse to stay away from you, the more likely she has lost interest and is leaning toward a breakup.
