Hi Millie,
I would urge you to get some help especially if you are worried about leaving your son with your partner. It sounds like you have a lot to worry about and maybe you could do with some support for yourself. I work for a charity called The Icarus Trust that supports people like yourself who are affected by the addictions of a family member or friend. if you would like to talk to one of our trained experienced volunteers please get in touch.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
Good luck.
