Welcome to the Sober Recovery Family!
You will find lots of information and support for yourself here. I recommend reading in the permanent (sticky) posts at the top of this forum for wisdom and to read some of our stories.
I am sorry that your AH has fallen back into old behaviors. Remember the three C's of addiction:
You didn't cause this
You can't control this
You won't cure this
Are you still active in your Alanon group? Pick up the phone and call someone if you feel the need to speak to someone immediately about your frustrations.
You can always vent your frustrations here, we understand!
