I have been with my SO for 2 years, and have not even met his EX. Previously on rare occasion would we have them on a overnight stay. I don't mind in the slightest having them overnight, that is not or never will be my gripe. Just recently we have had SD (11) and SS (14) every weekend, as EX has just got a new job Kudos to her. I do not want to replace her, they have a Mother. It seems the "honeymoon" period is over in my relationship with the stepkids. SD seems to think that she rules the roost, and no one else has any input as to how the weekends they are here run.
