certainly the adrenaline high, and attendent crash had it's place in keeping me in a dysfunctional relationship (although less so this last one than the one before), but it is by no means the whole or even the biggest part of the reason why I stayed. Nor can I speak for anyone else, especially those who become enmeshed in their children's siblings, or parent's lives, which are different dynamics than choosing to stay with an addicted partner.
