You didn't
CAUSE this.
You can't
CONTROL this.
You can't
CURE this.
Definitely get yourself a copy of "Co Dependent No More" by Melodie Beattie. It is very reasonable on Amazon. Make sure when you sit down to read it you have a 'highlighter' pen handy.
Read the 'stickys' at the top of this forum and some of the threads.
Please continue to post and let us know how you are doing as we do care very much. Feel free to rant, rave, vent, cry, scream, and yes even laugh.
