Hello Roaming bird: Sounds like this person has moved on for whatever reason. Perhaps she's trying to avoid being around other persons who struggle with mental health issues, as a way of trying to remedy her own. It's unfortunate she can't just come out & tell you what's going on. But it's her choice. We never know what may be going on in another person's mind or what may be happening when we're not with them. I wish you well as you move on...
