I have recently come to the realization of what makes me feel content; what makes anyone content. I know that you should never measure your happiness on your relationships with others. As long as you know who you are as a person and are happy with yourself, you will be content in your relationships as well. And if you are okay with being who you are and where you are in life, it only makes you stronger and nothing / no one can break you. It's something you have to learn and find by experience.
