Just adult responses to childlike behaviour... there is a compulsion to get sucked in and respond to the negative behaviour at the same level.
Your spouse shouts, your instincts are to shout back.
your spouse lays blame, your instincts aer to blame back
Your spouse argues a legal case, your instincts are to argue back.
DETACHMENT means NOT followoing your isntincts. It means distancing yoruself from the problem such that you can manage it properly and NOT allow your instincts to drive your responses.
Your spouse shouts, you ignore the shouting and state your terms of agreement
your spouse lays blame, you ignore the blame and state your terms of agreement
Your spouse argues a legal case, you ignore the argument and state your terms of agreement
Consistent, adult responses to childlike behaviour are giong to save teh day here better than acting in kind... panic, thrashing, impusive choices, all of that is your SPOUSE.. don't do what they do, no matter how much your instincts are driving you to do so... its NOT HEALTHY or constructive
