very few, if any, "relationships" are that well thought out.

We FALL in love and sex is natural. Things then get so complicated that we can't see clearly.

As much as I like your philosophy, it seems to me it is hindsight psychology and of little use as a logical plan going in.

Love and heartache are sisters. In my view, we are better equipped to have no expectations of permanence in any relationship.

But then, it is likely that I am the one that missed something.
