Oh sure... my wife is not an alcoholic... We've been married a long time with a good relationship that I did not trash, thankfully... But yes, some distance has opened up as I have worked through the steps, recovery... So I can at least reassure you that you are not alone or crazy...
Why? I have actually thought a lot about that... Is it because the journey of recovery is one we take alone? Yes!! Is it because we are no longer drinking buddies? Yes!! Is it because I interact with others slightly (or a lot) different? Yes!! Is it because my libido and our physical relationship has changed? Yes!!
Anymore reasons? I'm sure there are!!
Let me say though that our relationship is very much intact and is recovering as well, though it has lagged behind my own...
