I do remember reading about some of those things. My T also changed like that suddenly too. Although it wasn't with time like that. She'd text me to check in on me sometimes and it helped hugely with my attachment issues (she was still out there, after all). She told me it wouldn't be happening any more because it was too friend like (despite the fact that it ended up being about one text from her and a reply from me once a fortnight or so). So I do know how it feels to have things shaken up suddenly when you don't really know why, or where you wen't SO wrong. I don't know if all my examples are actually helpful for you. I do want you to know that I hear your pain though!
