Loving someone with substance abuse is complicated. There is no right or wrong. When you are in it-you are in it. Being uncertain of what to do is normal. Breakdowns are to be expected. Only you can choose-everyone will have advice. Sometimes we get addicted to our addict. If you haven’t read CoDependant No More I highly recommend. It may help you understand yourself more and decision making may come easier.
Age doesn’t matter in addiction-I’m almost 40 and wondering “should I stay? Or go?” I know I should go-but I’m not ready.
Hang in there-you are the decision maker for your life. Rest if needed-and take time away from opinions and let go of some of the weight of holding others perspectives and advice.
Take care
