My thought on selfishnes and addiction differ from yours.
They are both true forms of love and are misunderstood by belief systems that are set up to believe in "the Good, the Bad and the Ugly" and to make or pass judgement from those positions.
Is unconditional love possible? You better believe it! You feel it in your heart as much as I do, but do you recognize the burden of acceptance to things abhorrent and repellant, and to validate those things as much as the things you find beautiful and nurturing? It is a hard thing, learing this responsibility, but on Knowing It, one comes to understand the insignificance of it all!
