Welcome to SR, Firegirl. The 3 weeks will go by quickly, believe it or not. Especially if you take the time to focus on yourself and your DS (dear son). However, if you use this 3 weeks to worry about your ABF (alcoholic boyfriend) and what he's doing or not doing or what will happen when he gets done with the program, it will be the longest 3-weeks of your life. You can't control whether or not he really works on his recovery, but you can work on your own recovery and take care of yourself and DS.

Actually there's a lot of very helpful information in all of the stickies at the top of the forum. Welcome and best wishes.
