Marcus has good advice there.
You see, in my personal experience, When a person hits a low and wants to quit, they tell themselves it's time to quit. Problem is, the brain has been rewired and when you take away the meds, there is a "flight or fright" response. THe brain goes into this PANIC MODE and tells you NEED MEDS!!!!!!!!
An addict is the best lier in the entire world. Deception becomes that persons main mental strength.
Only a determined and dedicated person can stop the process. No one on earth can make that person stop except him/herself - Well, that and being locked up behind bars.
You have a MAJOR life choice ahead of you and no one but yourself can make that decision. It's my only hope that you do what's right for YOU and your Child. Nothing or no one else matters but the well being of you two at this point. *IF* BF is not willing to make the sacrifice and sit on the fence, run.
*IF* BF extends an honest and dedicated hand out for help, then you will know what to do. Keep in mind, during the recovery phase - NOTHING can be left to guess!
