My Dd had planned to move in with her partner in a flat together in the new year. They both currently live at home. Tbh the cost of living makes this impossible. I am toying with the idea of letting him move in with us for a while. But I know once he's there it would be extremely difficult to ask him to go. Has anyone done this? What are the downsides? He's very nice - works full time - would pay his way. My house isn't huge. They would need to share a room. I have another DC who is out a lot with friends.
