From what I know and heard from al anon and aa, it takes up to 2 yrs once they stop drinking to feel real emotions.
They may some emotions after 7 days sober, but not healthy emotions.
Frag: My last relationship was like that, start, stop, no contact etc. My ex was not boring though, I loved his company. We had many great times, but we both became emotionally dependent on one another.
We are no longer together, but both work our separate programs because this break up shook us to our core.
Frag, maybe you can look into getting into Al Anon, It's helps detach and look at your own shortcomings.
It's easy to look at the addict and forget about our own messes.
