Sorry I disagree with almost everyone. If any of my 3 DSs needed a home whilst I had the space they always knew they could come home. It never meant they wanted to live with me for ever. It was just a place they could come to when they needed a little extra support. All of them moved in and out at different periods of their life and one brought a child with him. Maybe I'm weird but I can't see the point of a beautiful renovated house if it isn't there to provide shelter for a family member who needs it.
Yes, we have done the same. But I think there is a difference here, is that Mamma66 has a strong inkling that this will not be a stopgap of a few months, but that he intends to live there forever.
And I think she is quite right to say that she does not feel comfortable with this. Totally fair.
