Hang in there Kerri, stay strong , and don't get caught up wondering if things could be different with your ex. I started my sobriety the exact same way some time ago.
Working through a painful breakup
now after 6 years.
A drink or drug won't ease our I pain for long, and it'll surely come back with reinforcements.
Stay strong and we're all proud of you
The guy doesn't care enough about you to stop his own additction. Find some new weiner and be happy.
Totally relate 
, but good for you for staying strong and putting yourself first. Who knows, maybe the loss will have him reflect on what he had and in turn, change his life around... could ultimately be a win-win situation
