First of all, when you married your husband you also married the kids and the responsibilty that comes with it. If they were with you full-time at that age, where do you think they would be? Hanging out with you and your much younger girls? Nope...they are at that age where their friends are most important to them. I understand that while this may seem to cramp your style, it is unfortunately a responsibilty that comes with the territory. They obviously love you and your family or they would be tickled at the chance to skip out on weekend with stepmom and stepsisters. Keep in mind that they won't be around all that much longer for visitation and enjoy what you are getting. Perhaps if you tried to plan something that is fun for the family to do (the thought of running errands or visiting my step grandma wouldn't be high on my priority list either) then maybe family time would seem more appealing. I know it is hard and probably a little awkward for you, but I really think it sends the wrong message to not try and make the time that they are scheduled to be with you a fun time for everyone. What teenager thinks it is great fun to hang out with a 2 and 6 year old? Unless someone was paying me at that age to babysit, I wouldn't have been caught dead playing dolls with my kid sisters. Just remember what your teen years were like and know that it truly would be no different if they were yours also. Good luck and remember patience and understanding during those teen years is a critical part of parenting.
