OK guys, I need your advice on a situation that has come up with DD.
For those of you who are newish and don't know her situation, DD is going to be 13 this month. She is "different" (to put it mildly). She is emotionally and socially very young (more like a 3rd grader than a 7th), she has severe learning delays (doing 4th grade level work in 7th), has epilepsy, auditory and visual processing and sensory integration problems. She is in a very specialized special ed class (other kids in there have Downs, Autism, CP, etc). Her classification is Multiple Handicapped. Her IQ was tested at 65 (for what it's worth--I don't hold much stock in those things!)
So anyway, she went to a camp this summer that was a special camp for kids like her. Had a BLAST! Met lots of nice kids, made friends, the whole nine yards. even had a "boyfriend' who is 14. Well, since she's been home, the only one she's heard from is another boy, named Alex, who lives in California. I met him the day I picked her up. He seemed nice, sweet, very clingy. Said he wished he could come home with her, becuase I seemed like a nice mom. (Not sure what his home life is like, but he was at camp the entire 8 week summer)
The problem is, he is calling EVERY DAY. And several times each day to boot! This is bothering DD. When he calls, she rolls her eyes and says "he's calling AGAIN?!?" (I've pointed out to her that she did this same thing to several people prior to this summer!) She really doesn't want to talk to him so often. And the BIGGER (for me anyway) issue is that this boy is 17!!

I'm sorry, but even with them being just friends, and him being 3000 miles away, it's not appropriate. And they WILL see each other again next summer. So if they've been talking on the phone every day until then...I can't even think about it.
So, DD wants to tone it down. i want to tone it down BIG TIME. How do we approach this? The kid is "different". No clue what his social skills are, or his history. He may be like DD and really have no friends, and feels she is his only friend, Sad, but still not OK with me! I don't want to destroy this kid, or break his heart or anything, but something has to give! If he called her once in awhile I'd be ok with it, but not constantly.
Any suggestions would be very greatly appreciated. I'm flying blind on this one!
