I'm a total newbie.................and as of yet not comfortable enough to tell "my story"..........soo I'll just comment here and there for now:
Frida, I don't believe he's a "nutjob"..............I believe there's 2 types of people in this world............those in therapy..............and those who SHOULD be in therapy..............your man, I believe, is perfect for the NC...........and give it as long as it takes..................he's been honest about his feelings............now it's up to you to show him what is acceptable and unacceptable to you............... I don't use the NC method as a weapon but more like a defense mechanism.............I must say, it has worked every time...............it has allowed the other person to get their thoughts together, without any pressure................and has allowed me to maintain my sanity.
