I have been reading this, today.
This is the part about empathy:
5. There’s mutual empathy. Another key quality of a healthy relationship is empathy. Empathy means trying to understand what your partner is feeling. It isn’t about trying to fix your partner’s concerns and problems, necessarily, but about being able to be there for them. If you can pay more attention to what’s going on with your partner and strive to see things through their eyes, you will find yourself getting closer over time rather than more distant.
