James, take this with a grain of salt because I don't have all the details down, and you're probably playing it up for us, but it really comes across as you grasping at straws and trying too hard with her. It's awkward being stuck with an ex in a flat, I get that. But if she wants you, she'll let you know (especially if you've been transparent about how you feel). I agree with shosta that some space would be good, provided it's ok in that Coronavirus crisis. If not and she stays here, don't game ulterior motives.
