TW,
You have an army behind you. Its the SR Army. We are a powerful group of people. You took your time and are executing this exactly as planned. You can do this. No one said that emotions cant be involved. I signed my divorce papers and cried my eyes out. The judge told the bailiff to get me a box of tissues. I didn't want to divorce the man that I still loved. But I knew there was not another option for me after 34 years of waiting for his sobriety.
Sometimes we need to follow our brain and not our heart. Sending hugs that you find clarity in all your decisions you choose to make.
