Success is only an illusion of ones importance to others...happiness with your inner self is much more powerful and truly the only thing you can control.
You have become super focused on your wife again....try to deny it, but it so obvious on here. Currently you are the one making the situation worse...not the neighbor, not your wife, and not your kids. You have been give the advice to give her space, but you still are not heeding that advice and instead are driving her away more and more. I really thought when you started posting that there was a good chance that you would fix yourself and with that possibly save your marriage.....but you have continued to focus on your wife with only small steps towards working on yourself....and we can all see how well that is working....as Albert Einstein said "Insanity".
Leave her alone, drop the bible, and look into your soul....that is where the path starts to finding your solutions....only there...no place else...and nobody can help you do it...you have to want to do it for yourself and do it yourself....that is how it works!
Please refrain from any mention of your daughter as a slut or drug addict. Remember that she cannot begin to respect herself until you give her some respect..focusing on her past issues only causes them to happen again...a self fulfilling prophecy. She is a good kid who loves you deeply.....return the same with respect and you will be surprised at the results.
