Re: how to get rid of an unwanted house guest.. :s
Either he is a pervert or he is a nice guy and trying to go out of his way to help his friends little sister.
You know your husband , you live with him 24x7 you should know how to deal with him.
After all this does not seem to be the problem created by this girl , she is being forced to stay over by your husband. Does she know that even if your husband does not want her to leave but you want her to leave ? If she does not know then let her know in specific terms. Don’t be shy about it.
