Sudden interest in appearance
If your love interest suddenly cares more about their appearance—spending hours at the gym, buying new clothes, wearing fresh perfume or cologne—but doesn’t seem to care whether you notice these changes, something may be up. There is a possibility that they’re doing it for their own well-being, but if they downplay your compliments or haven’t expressed this to you, more often than not, they are doing it to impress someone else.
