Couples who stay together the longest report having a stronger bond because of the unique or “novel” experiences they’ve had together. Working as partners to overcome obstacles is essential for a couple that wants to stick it out when things get tough. Practicing teamwork, whether in child rearing or competitive sports, can help strengthen the bond a couple shares. They should look for opportunities to do unusual things together and activities where they will have to work as a team to succeed. It may also be helpful if they take notice of how they’ve changed for the better since becoming a couple.
