each person has a lot to offer, but may not always offer it. As for relationships what I have come to understand is that for someone to fully be able to commit that person needs to be independent in the first place. When people become dependant in a relationship they do merge their resources like emotional energy, descision making and other things. Yet the problem is that with no healthy boundries this often results in a false sense of personal growth. The story often goes 1 of the 2 starts to hoard all the resources, simply because they are there for the taking. You can probably imagine where that eventually will lead to... As for commitment to really function it is a matter of being able to switch between independence and interdependence. This way both can keep growing and maintaining a healthy intimate balance. Thing also is that many people are kind of used to taking instead of giving and are looking for what they can get out of the interaction. In a sense it's form of emotional poverty I could almost call it. Pretty funny to say this in times when the mordern world almost has more than it could wish for. Yet there is this law that when someone gives something most people feel obligated to give something back. Expecting it is a whole different thing but all relations are exchanges. Really a matter of finding the most fair deals regarding to all parties involved as in win/win.
