I just want to mention that although I may seem a little harsh in my assessment of the impact and commitments that "third's" have within relationships... I am one. Not in the sexual way, but in the family way. I have thought about these things extensively: my commitment, contribution and impact. I accept and know what I bring to the table and what I don't.
