Selfless

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

Relationships is not as a bank that you run to when you need to make a quick withdrawal. Or the stashed away credit card that you pull out when needed for an emergency transaction. 

Relationships are built on how much of your love you are constantly willing to give, for the satisfaction of the other person you are involved with. If the other person is equally doing the same thing or more;  then you are well taken care of. 

But if it is one-sided....then, that's a troubling road you are traveling on. Re-evaluate....
