The definition of a healthy, romantic relationship varies from couple to couple, however, the one thing constant in all cases is that a relationship is a two way street, and efforts need to be made by both parties involved. For any relationship to become strong and stay strong, you need to work on it.
One of the most important things you need to keep in mind while working at a relationship is that communication is absolutely necessary. Healthy and happy couples always know how and when to communicate the right things. It doesn’t always mean that you should focus on the good, and push the bad under a rug. Instead, you need to address and deal with every issue as it comes, by cooperating together. For any long-lasting and durable relationship, you need to be able to truly talk about what you think and how you feel without any awkwardness or resistance.
