it's when you are indifferent to your S's actions, thoughts or feelings that you're done. When you don't spend time thinking about what they are doing, and who they are with. When you don't wake up in the morning (or 3am) thinking about them or go to sleep hugging your pillow wishing they were there. When you get through an entire day without thinking of them at all. When you don't search for them anymore... driving by, stopping by, checking out FB for any changes or evidence of other people. When you stop spending your energy thinking about your S, and put the focus exclusively on yourself and your needs, your plans, your life.
