Another issue that can come up when an addict enters recovery is a shift in family dynamics or just intimate relationships as a whole.
Your wife may have gotten use to the roles of you being the alcoholic and she being the enabler or co-dependent, or even just "not the alcoholic."
As you go through these changes in recovery, she too will have to undergo some changes as well and that can be uncomfortable for both of you. Perhaps marriage counseling with a professional who is familiar with substance abuse can help you both work through these changes together as a couple?
