What are your thoughts on a new girlfriend staying over, my 25 year old stepson first invited his gf over without checking with us, I addressed this with him and said he needs to respect that this is our house and should check with us first, the next time he did ask us first but I am wondering what blboundaries to set as I dont want her here during the week when we’re working or every weekend for that matter, her parents are strict so don’t think our son can stay there, what are you thoughts or experiences please?
