Empathize with you partner, put yourself in your partner's shoes and think about how you would react in the same situation. As the old saying goes "Never judge a person until you have walked a mile in their shoes" rings true to life. It is easy to pass judgement on another person when you have never been put in the same situation yourself. You have to think, "Would I do the same thing, if I was in the same situation?"
Enough said, I think you can figure out empathy from here.
