Thanks for your honesty and sharing your struggles.
It isn't easy to break a lifetime of ingrained behaviors and beliefs. I've worked hard for years now on my codependency issues, and can still slip back if I am not vigilant.
I hope once you quit smoking pot that things will become clearer, and perhaps you can make some decisons, or at least deal with the current situation with a clear mind.
Please keep posting and let us know how you are doing!
