There is no easy solution here, it shouldn't be her son's responsibility to talk to her either...He is a kid who didn't ask to be in this situation.

However you chose to be with this person and even after witnessing the severity of the problem you have stayed, like many of us do in the hope things will get better.

You can't change her, or her behaviour, but you can change how you choose to respond to it. Easier said than done, I know. We get into a way of being and it's difficult to get out of.

If she isn't ready to dry out there is nothing you can do, and I am telling you this as a 24 year drug addict.

She has crossed physical boundaries, and is putting herself in danger just to get a fix.

I would suggest getting out while you can, before she becomes too Ill or so infirm you are left to nurse her to an early grave.

I might also request you consider her son in all this, he doesn't need this anymore than you do, and when you got with her he became a part of your life and to some extent responsibility. If you could manage to not cut him out at the same time as exiting the relationship, that would probably help him alot.

I also understand that would be difficult, but that's part of the responsibility of getting involved with someone with kids.

Whatever happens I wish you all the best for your future.
