Validate specifics yes, but not give them hand grenades no...

saying something like "I should be putting more time into our relationship and not focussing so much on my school" or some such because THAT will show them you are CHANGING a bit and give them some HOPE

But just saying open ended things like "we need to move forward" is going to be interpreted as "We should file for divorce, I am in full agreement"

Validate feelings in such a way as to offer HOPE and to show CHANGE for the BETTER

But no, don't say ANYTHING that can be misinterpreted to your DETRIMENT... And waywars LOVE to MISINTERPRET, so you need to keep things

Simple
Concrete
Hopeful

Always keep these three things in mind.

"I do NOT want a divorce - I love our family" is good
"It's time to move forward" is BAD
