I would never take a long distance person and move them in as a "lover" or "equal".
Admittedly-we have a "open door" policy for ANYONE who needs a safe place to land.
For examle, my sister is living here now in the midst of her divorce-but she intends to get a house once her divorce is finalized.
We've had families stay here for a few months when trying to recover from a major financial loss.
We have had children who stayed with us due to family problems, getting kicked out etc.
But in every case (well except my sister) we don't have a "partnership" relationship wtih these people. It's GREAT to be able to build a family like that-but the reality is it takes time to build relationship and confidence-especially with kids.
