"Some of the biggest challenges in relationships come from the fact that most people enter a relationship in order to get something. They're trying to find someone who's going to make them feel good. In reality, the only way a relationship will last is if you see your relationship as a place that you go to give, and not a place that you go to take. "- Anthony Robbins
I believe both giving and receiving love in our marriage is an important part in sustaining it. However it is important to find that balance so neither spouse is giving too much and receiving too little, or vice versa. This is why the concept of compromise is so important.
It is also important to realize that as much as it is important to give, giving too much can be detrimental to a marriage as well.
