Our first years were filed with abuse and chaos
We separated and he went though rehab. He made a vow that he would never drink again.
He has misused/abused the anxiety drug. I just recently found out he has also been drinking.
He has also lied many times to me about both the drugs and the alcohol. His bad choices, his addiction, and his chosen lifestyle is NOT YOUR FAULT. He is throwing your A back in your face as a way to distract you from the real problems here. The problem is that he is drinking and drugging again. He knows it is wrong but does not want to stop. He needs to get back into rehab, and It sounds like you need to seperate from him again.
I think you know that, but you are hoping that "if only" you could make him happy again. "If only" you could erase your A from the past, and "if only" he could finally learn to trust you again, then he would no longer feel the need to drink.
But deep down inside, you know better. in your own words, you said that the first few years were filled with abuse and chaos. But eventually he got help and stopped drinking. You have forgiven him for the abuse and chaos. Yet he keeps throwing your A in your face? From 8 years ago? come on now, you know that is a load of crap from him, don't you?
Please get into Al Anon, today!!! And start building a support group for yourself. You can not fix him. But you can fix yourself. and if he eventually gets back on track, then he can re-join you. If not, then you (And your Boys!!!) do not need him dragging you into his he11 any longer.
