Do you agree it's a mistake if a woman moves in with her boyfriend with the expectation of a proposal one day?

If she moves in, thinking that it's really a step towards marriage in the future... and in her mind really expects a proposal one day, isn't that a mistake on her part?

She shouldn't assume things, build fantasies in her head nor think that's expected after a while. Moving in is just that, moving in. Otherwise why are there too many ''We've been living together for 5+ years'', why isn't he proposing?

Too many of those stories. Too many women build those fantasies and it says as that; as her own fantasy, her own dream that she'll never have as long as he's keeping her as perpetual live-in-gf to enjoy the moment.
