A "temperature check" is basically pressuring your spouse to tell you where they stand in regards to the M. Per DB'ing it's not advisable, but some of us do it anyway and it never results in the revelation we hope for. So don't do it What do I wish I had done differently- well I wish I had not had expectations that the hugs and W signing us up for RetroV meant that a turnaround was imminent. I've offered advice many times to others to be patient and not push things, I should have taken my own medicine No regrets, if it was a backslide it was a small one and it helped me to recognize that I needed to get back to DB'ing basics.
