I am so sorry that you have to go through that. I am on the other side... I am the addict and my husband is the one who has had to suffer through it. I do not isolate myself quite like your ex but I have done things that make it harder for him to try and support me. I guess in the end the only saving grace that has kept us together is honesty. He lets me know exactly how he is feeling and I try to let him know what it feels like to be an addict. We have been together for 8 years now. I was an addict when we met and this will be the first time being sober while in our relationship. I hope he loves the sober me as much as he loved the pill popping fun time me.
