I think you're wise to take those maybe-positive signs with a grain of salt, especially with OM in the picture. Same for being realistic about how that R will go. For me, the worst thing is being blindsided---I react emotionally before I take a breath, and that's never good. So if she tells you the day you move out that they're (back) together, you'll be able to breathe.
And good for you for letting her be nice to you. The advice to choose when to take her up on her kindness is also sound. You recognize what her LL is, and you don't want to shut that down. Slow and easy does it.
Take care. I can't believe you're a Saints fan, man.
