5. Communicate freely
Try not to keep any secrets from each other if you can. Sure, a little white lie here and there never hurt anyone, but it is always best to be honest with the person you care about. If you think he made a bad decision investing in that particular block of shares, then tell him what you think. Sure, the truth may hurt and spark a minor disagreement, but at the end of the day, your partner will thank you for being honest. Being able to communicate freely with one another is one of the fundamentals when it comes to keeping intimacy alive in a relationship.
