Establish a strong emotional bridge with your partner
Maintain a reliable emotional link and do not let it become any weaker. This will prevent both of you from looking for someone else. Emotions will make you feel very close to each other which will make your relationship much better.
Never belittle each other
Try not to make fun of your partner. This tip is an essential part, especially if you know that your beloved one is a sensitive person and does not tolerate jokes that can make him feel smaller, weaker or less intelligent. It may hurt the partner and ruin your bond.
