My Fault

Well yesterday really stunk, and I am not sure how today is going to go.  Saturday night I told my husband I wanted a divorce, and now yesterday he got a DUI.  Of course I feel guilty now that this is my fault.  If I hadn't asked for a divorce, he wouldn't have been drinking at 2pm in the afternoon and driving.  Even one of the kids said this is my fault.
Lucky for me I have good friends who helped me realize this is not my fault!  Yesterday could have been any other day where he had been drinking.  He has been this way for years, and this was just another day.
I still can't help but feel some guilt though.  Going to try to find an Al Anon meeting today for additional support.  Why does everything have to be so hard?  I just want one day to go by where I am happy, guilt-free, and free.
