No child needs or deserves an actively addicted parent. No child should have their bank emptied by an actively addicted parent and no child should have a mother worn out from working two jobs to support the family while the father uses drugs.
I'm really really sorry for your situation and your pain, but I have to tell you straight up that it won't stop and it won't get better any time soon.
I watched my son destroy two families, his first with a lovely son and his second with a dear little daughter. He stole, he brought drugs in to the home endangering the child and he was incapable of being a good husband, father or provider because he was (and I believe still is) an active addict.
Take a good read around, it may help you see what may be ahead for you as long as he is using.
I'm glad you joined us and hope you find comfort and support here.
Hugs
