I have witnessed first hand what meth can do to a person, it's heartbreaking, because one of those people is my oldest son. I also dated a woman whose daughter also used it, she would lie, steal, etc. I hope you can find a place to think about yourself and your future, because there is absolutely no future with someone who uses this. He is the only one who can fix him, if he shows no wanton desire to do so it will be a big waste of your time.
