Wonderful!!! You did fantastic! :ghug3
You are thinking clearly and you are spot on with your decisions. You realized right quick that your ex is no one you need to be talking to about this. Communicate with your son and let him know what you will and will not do.
So many times, people think that if they just move away somewhere, all their problems will be solved. The thing is...wherever you go, there you are. Your problems are inside you more than anywhere else. Sure, you might get away from known bad influences, but those bad influences are everywhere!
I'm so proud of you, I could just burst!
