Finally got through to a person at Retro. I had filled out the registration online over a week ago and hadn't heard anything. The woman told me that they've been having issues with the system. Our weekend should be Oct 12-14. She also told me that it would be okay to do the first weekend and follow up sessions in different locations. Good news.
Told the W that everything looked good for Retro. She is still onboard with the plans, also good news.
W is going to our counselor tonight for an individual session. Hoping this goes well also.
