LOL, I just read some of a book on brain chemicals in a bookstore. Should have picked it up, wasn't sure if it would teach me anything useful that I didn't already know.
Puppy is right, the addiction to the A is real, can be measured with medical devices, and is HIGHLY addictive. God knew what he was doing there for sure. He wanted to see the continuation of the species and man is more likely to stick around with that PEA floating around, and later the oxytocin and vasopressin.
Part of why I feel the A is not over, just interrupted if anything at all is that I don't see signs of withdrawal. Sulking, anger, outbursts, withdrawing. He is joking with kids, running around the house with them, feeling pretty good about himself. When caught on FB I asked if he was emailing her and he said "of course not, I told you I'd tell you if I decided to do that again." This means nothing to me, it's his behavior that says either he's still in contact or else plans to be in the near future b/c those chemicals are still floating around and maintaining his high.
