My kids (GBG) are now 15 1/2 and Sophmores in HS. I was concerned through middle school because of the whole drama. I seems tha t the kids were tuned to who was going with what and it became their soap opera. Even though i was not officially informed I know my kids had "relationships" through the middle school years.They never went out anywhere but "were going out in the school" Even though my DH might not agree, those relationships will help them establish the pattern for the future relationships. It is the time to have conversations about growing up (birds and bees) and what to expect and what do you expect from her in the future. As far as this not being an issue in a Christian School, as per my daughters friends experience they deal with the same just keep it quiet from adults... I can tell you the stories I have heard.
There is a great booklet from the American Medical Association, directed at teens and preteens and it talks about deciding to delay the decision to become intimate with someone and why. I read it to the kids, one of their friends and the girls boyfriends altogether and let them comment and ask questions. It was a real cool experience and the boyfriends know what i expect from them.
