im curious why you need these requests is it fear for her saftey, you don't want to sit up worrying about her, or is it becuase you don't like the idea of her spending the night with someone else?
personally i would actually hate those requests made on me, i usually come home whenever i want, if i choose to stay out then i stay out, as long as I let my other partner know that i am safe and not to expect me home that seems to be ok,
i like to be spontanious and having those kinds of restrictions would limit that
also it would make me feel like im being treated like a child,
that is just my opinion and my relationships are unique to me so im not saying that you are being unreasonable only how i would feel if my own partner(s) started making requests like that to me
