How to ask her to move out?

[Ctyh]

My friend was suffering badly with depression and unhappy in her accommodation so I asked her to move in with me and my husband so she could get better.
It’s been 5 months and she’s back on her feet and in a great place. I think it’s time she moved out again but I don’t know how to ask her. Any advice?

Maybe approach it generally, ask how she's doing within herself and when she's thinking of moving on from this chapter of her life. Did you make it clear it was only a temporary thing for her at the beginning ?

Say “it seems as if you are back on your feet. I think it’s time you moved out. Would you like some help finding somewhere?”?

Be direct, as Bigmango says...
‘So great to see you back on your feet now, have you had any thoughts about where you’re wanting to live. We’ll help you look’
