My best friend has been put out of her moms place. I told her that she could stay in my extra room. Keep in mind that we’re both in our early 20s and I have a 3 year old as well. She has been here for about a month now. She has her own room closet and bathroom. The question is , how do I bring up the conversation about her chipping in with rent and groceries? and how long does she plan on staying. Neither one of us has brought up anything concerning it but I feel it’s a conversation worth having.
