<p>Well…at 17 I was not living at home with my mother, but instead with my (also 17) yo boyfriend, at his parents home (and we were both in HS). That was 37 years ago, and while times may have been different, it worked for us. We lived together for 2 1/2 years. I am still very close with his family, and his children and his brothers children consider me an aunt. </p>
<p>Because of my own (positive) experience, I would absolutely invite my son or daughter’s SO to stay over, but it would have to be ok by the other side as well. I would not go against that.</p>
