I'll give you a little "heads-up" that I wish someone had given me when my kids were teens:
Around ages 14-whatever, they really start pulling away from you.
DO NOT TAKE IT PERSONALLY!!!
They want to hang out with freinds, they don't want to hang out with you anymore. The world is a big wonderful place to them and they wanna see it all - WITHOUT YOU.
Like Poopsie said, just make sure your contact with them is always positive and upbeat. Be the "ROCK" they can swim to when they think their world is falling apart and then.............let them go again.
Eventually, they come back to you.
Trust me.
My kids are 18 and 24 now, and they tell me alot of what's going on in their lives and they tell me looooooong before (and IF) they ever tell their JW dad. They both say they can't talk to him.
