Danielaf89, Welcome to SR!
The OP started this thread almost 9 years ago. Thankfully, she did find out that her husband was OK.
Sadly, the disappearing act is not uncommon among active alcoholics and addicts. So, what we get to decide is how we are going to respond.
My stepson disappeared for several days, once, and we filed a missing persons report. You have that option if it would help you to know that the police are keeping an eye out.
In the meantime, please take good care of yourself and your precious little one to come--how exciting! You will all be in my prayers!
