<human>: Could you distill the essence of the text into 1-3 sentences?

They have known each other for a long time, since high school. He will be living in his parents house for two years while they travel and he has asked her to move in rent free during that time to keep him company while his parents are gone. There would be nobody else moving in so just the two of them in the place.

She had already told him that she will likely move in (she said this before talking with me about it). I talked with her about my concerns about that situation and she told me told me she will not move in. Instead she will be going over for dinner a few times a week and will only sleep over if another friend is there. I don't really like the idea of her sleeping there at all. 

Lastly it's been over a month and she still hasn't told him that she won't be moving in.
<bot>: SO wanted to move in with a male friend told me she would just have dinner a few times a week and sleep over occasionally she will only be sleeping over if other people are there. Has yet to tell him about not moving in.
