Okay, then I tell her this: "Look, right now we're not a couple, there's no indication that we're working on becoming a couple again, and I'm not interested in acting like we are if we aren't. I enjoy spending time with you, but I really value and enjoy the time I am spending on my own these days, and I want to keep that time "on my own". If we decide to get serious about working on our R then maybe we can start doing some more things together but, for now, I want some time to be on my own." Or something to that effect.
That is some outstanding script-flipping stuff right there. Takes all the power over this whole situation out of her hands and puts in yours. You are the master of your future. Nobody else.
