10) How Do They Treat Their Loved Ones?

When someone speaks about the person closest to their heart, the way they portray that person can reveal a great deal. 

If they roll their eyes, let out an exasperated sigh, and say, “Oh, it’s so annoying that X is always…,” proceeding to disclose every little detail about their supposed close companion, it may indicate that they are dealing with some significant challenges.

Perhaps they are projecting their insecurities onto that person, or they may have experienced difficulties forming genuine connections. It is even possible that they exhibit similar behaviors to those they complain about.
