But I do view D as a way of disposing of people - emotional murder, if you like
Jo, exactly, emotional murder is one of the best descriptions of D I have heard.
"Puppy love", "instant lust", etc are signs of immature love, not real love. I think mature love is a choice. I chose not to act on the opportunities to get involved with other women when I was married to Dawn. I couldn't always stop the fantasies but I could use my maturity to know that the lust would not last forever so don't commit "emotional murder".
