Ur r doing really well, I'm also tappering down from suboxone. So I know what ur going thru. But as with the fiancé I can't say I know what ur going thru... What I do know is while ur trying to do better for urself , it seems u can't do that with him around doing drugs, even if it is just pot, it's still a drug and yes u defntly can go thru wds from it. I sounds to me that u have already talked about his drug use and alcohol use and he doesn't wasn't to change? Maybe u need to think about how important u getting clean is? Think about once u r clean and sober is he going to be a trigger? I had a best freind n the similar situation as urself and sorry to say that they're not togeather anymore... But she's still clean! I hope I've helped some....
