I have raised my step sons full time since they were 11, 9, and 7. We've always gotten along well because we are a Christian family and we always had the boys' best interest at heart. The problem is with the youngest who is 18 years old now. He is in his last year of high school and since he turned 18 he thinks he should have all the freedom he wants. He does not understand why we wouldn't let him go camping with his girlfriend and another couple. He swears that nothing sexual would happen, but we just don't want him in that sort of overnight situation.

Well, i thought we didn't. My husband started to give in yesterday and I told him I didn't understand why he couldn't stick to his guns. He became very defensive and angry, yelling at me. We never fight! Should we just let the 18 do whatever he wants because of his age? I really want him to abide by our rules as long as he still lives here. Why is this happening? What can I do to make sure it never does again?
