Hmmmm. She threw you away the first chance she got? You were sober for 15 months and then stopped going to meetings, didn't have a sponsor and weren't doing what you needed to do to stay sober. But all those things are a choice. You chose not to do them. Not her. Maybe she felt like you threw her away. Just a thought. That's why recovery comes first. Just take it as a lesson learned and move on.
