She was like an illusion for you and you have done the job for the illusion. You may fallen for her but from her prespective it may not the same like you. So in the middle you worked 2 months which was in vain as she left it. Your focus divert on her and so you didn't think too much about how difficult it was working for you in the place.
Yeah, her presence there made everything else seem okay to me even though they weren't. But I came back to reality the moment she left.
