Post-rehab is still a very hard place to be. My STBXAH only lasted a month before relapsing the first time (and he lied about it for another 2 months.) About that time, I realized I just couldn't do it anymore and ultimately he went back to rehab. He didn't realize it at the time, but I arranged it so he couldn't come back here, and instead flew home to his parents when those 60 days were up. He had planned to visit them, but I figured the least I could do was get him safely detoxed before he went out there. I packed up the majority of his stuff and my family drove it back to his parent's home.
So yes, I got tired of it all. And I left. Or rather, made him leave. Life is SO much better now.
