It is ABSOLUTELY an addition. Just Google "love brain chemicals PEA" -- there's more than 200,000 entries! It's a physiological fact, and it even shows up on CAT scans.
That's why so many of us are pro-exposure and the need to institute a bullet-proof "no-contact/transparency" plan if a wayward spouse is ever going to rid themselves of the affair partner. Once you realize that they ARE addicted, the only reasonable conclusion one can come to is to FIRST remove the addict from the source of their addiction. Without that, nothing substantial can be accomplished.
I'm sorry I'm not familiar with your sitch -- does your husband deny the affair? Admit to it and refuse to leave it? Or admit to it and say he'd LIKE to leave it, but can't?
My wife used to literally STAND with her cellphone in her hand, holding it out in front of her at my son's baseball games, just waiting for it to vibrate with the sweet dose of her fix. It's really quite pathetic.
