Oh boy!

This really isn't what you needed at this time. You really didn't need any connection with this man. BUT you cannot take it out on this precious baby. You'll have to think of this beautiful child as a gift from God, and having nothing to do with this man.
You are MUCH better off without him. He was abusive and controlling. You're in a better place with your Mom.
Now you have to work on staying CLEAN especially for your baby's sake! You cannot use now, or else your baby will be born ADDICTED! Have you ever seen a child born addicted? It's HORRIBLE!

The poor baby has to go thru withdrawal, and that's painful. So seek help to help you stay clean.
I wish you all the luck in the world. I hope you'll stay here and keep posting. We hopefully can help a little.

God bless and take care. Hugs, Lee
