Mike, What you're experiencing is pretty normal. I know that I have thoughts that "it could happen again" and this is after being reconciled for about 18months. When you've experienced a traumatic event,there is bound to be residual feelings. Certain things they do or say can trigger memories/feelings. Please understand that these insecurities of your's will pop up frequently and don't act on them.This is probably why you feel a lack of confidence and want more reassurance/intimacy with your wife. She has radar,so don't appear "needy" or "pushy". You're an expert on these things and you know what works and doesn't with her. Go back to DBIng strategies and use what has been successful. She is having her "ups&downs",too.
Keep your PMA going and have patience with her...Jenny
