I grew up without my Dad.

Would I have made some of the choices I did anyway? No real way to tell, but my guess is no. Was I angry as a kid? Not until I hit my teenage years. Then it all went to hell. Could it have anyway? Yep. The only blame that gets placed here is on me for making those choices. I was lucky enough to find my way out. different people have differnt results with that.

Can kids do badly even in happy, healthy homes. Yeah, they can. There's just usually better resources for them.
