Does anyone know if there is a specific evolutionary purpose to wanting what we can't have, and why the desire to have something we know is wrong or that we know we can't have seems to increase to sometimes obsessive levels (and then decrease if we get what we want as we realise we don't really want it)?

Progress, evolution, improvement, the list goes on and on. We are always looking to do better, go farther, go faster, have more. That is how we as a species has gotten to where we are today. If we did not have that desire we'd all still live in caves!1

You don't have to deal with the reality of having it, struggles and all.
Some people only find people already in a relationship attractive. By wanting something they can't have they don't run the risk of getting it and ruining it.
It can be easier to dream than put in the hard work required, or be disappointed by the reality.1
