Dad and MominMinn,
what you sons did is reprehensible, horrible behavior that cannot be explained away in any reasonable manner. We all recognize this story...years of an uncomfortable not to say dysfuntional relationship where you two accommodated, apologized, felt guilty, and thought that love would show the way...during which they were mean to you, took advantage of you financially and materially, and drained you emotionally. And then Something Big Hit, where even loving guilty, slippery slope mom and dad could see that what was happening, what the boys felt entitled to do, was totally totally wrong. So you snapped.
Dad, you did the right thing, the only thing you could do and still look at yourself in the morming, as a dad (yes to them as well as your younger two), spouse, man, person. People who treat you like that CANNOT STAY IN YOUR HOUSE. You can't wake up and go about your day with people like that there. They can't wake up and go about their lives if they think that sort of thing is ok, acceptable in anyway.
Having ridden this roller coaster for years, I know the regret and second guessing and tearful nights and days that comes with this sort of action, on their part and on yours. The sick stomach, aching eyes, head ache, unshed or shed tears. I am really really really sorry you are in that place now...but your actions are the one hope you have of getting through this state, moving beyond it, and not finding yourself in quite such a bad way again.
We all love our kids here. We are all mortally wounded by their behavior, their unwillingness to accept our love or our role-modelling and parenting, we are mortally wounded by who they are turning out to be (I make that active because I too still hope this is a process and my difficult child will magically turn out some differnt way in the end. He won't. Others may. )
So you found a good place. We will help you, listen to you, stand with you.
Keep posting, and good luck.
