Tragic necessity? Aren't we being a little too dramatic?

The quote of the day reads:

One realizes that human relationships are the tragic necessity of human life, that they can never be wholly satisfactory, that every ego is half the time greedily seeing them, and half the time pulling away from them.
---Willa Cather

Now my friend Willa was quite an interesting character. What she writes (both in her books and the random quotes from her I have read) reveals a lot about her. And many presume that she preferred to "taste the rainbow" so to speak. But as much as this quote is crazy revealing and seems on the bitter side of life, the more I read it, the more I tend to agree.

Relationships in all forms seem to be an awkward kind of dance to reach a comfortable middle ground from both participants. Add to that, each individual is constantly evolving, making the definition of what exactly is the middle ground just as fuzzy. I have seen the tug and pull that she refers to. I have been the seeker and I have been the one pulling away, as we all have at some point. No real lesson or overarching sum up. Just one of those human nature things that makes one laugh cause we are all so silly. Does that make it them a "tragic" necessity? I dont think so. It sure keeps life interesting.
