Not just that but what you might not understand is that those painkillers actually had a lot to do with his emotions. Not that he doesn't love you off of them I'm sure he does but he can't feel anything but pain at the moment without them. They do something terrible to your body. They pretty much replace any real feeling that you have and you're okay when you take them but when they're gone it's like your body shuts down and you actually get emotionally and physically sick. He will get better after that first hump in the beginning right now I'm sure he's just trying to figure out how to handle this. It took a couple weeks before I even decided if I wanted to live or if my life was really worth it to me or anyone else. It's just a really bad mess to be in but I'm sure he'll come around it just takes time. Another factor is you aren't around him now and he probably feels ashamed that he messed something amazing up.
What does change really means? Did you meet him before he had an drug issue? It’s hard to know what’s coming. It sounds like he has more in his hands then he is able to handle right now. You are trying to make sense of a very confusing and unstable time . He has to get well himself before he commits to anyone and/or anything. He is probably scared and ashamed. He probably feels uncertain of his own wellbeing and future right now and is not ready to make you promises he can’t keep. It’s hard , I know, but is his reality right now. Hopefully he will be able to be healthy again and be there for others…
