From October 2005:
“Selfish altruism”. Take for example two altruistics dating each other. They continually do things only for the other person, and in turn, all of their selfish (ego) needs are satisfied. However, an altruistic in a relationship with a non-altruistic results in an unhealthy relationship. The first one gives and gives, getting nothing but companionship in return. The latter gets consistent, whole-hearted attention, but is never aware that s/he needs to give a little as well (or a lot). Neither individual can grow, or change with the other. Both’s weaknesses (if you want to call them that) are emphasized. The altruistic never realizes or accepts the importance of getting something in return and the non-altruistic never realizes the importance of giving back.
