Have you both tried to kick the drugs? Meth and Bath Salts are really heavy mind altering drugs, I can't imagine being on both at the same time.

I'd recommend you each try entering detox first. Separately. Then finding a support group where you can both go together and try working this out.

Joey, God forbid you and B don't work but drugs seem to be the root of both your relationship issue's. If you really Love B, you have to decide what you love more. Drugs or B's Love. Love is way better in the long run. Drugs only ever end in bad situations.

Good luck with your journey. Good luck hope it works itself out between B and yourself.
