Hi Chloe1994,
Welcome to the Forum, where there are lots of people in similar situations.
I’m sorry you are in this situation, especially being pregnant as well, you should be having all the support from him but sadly cocaine will always come first, unless he wants to give up. Personally I would run for the hills and look after you and your baby, go back to your family who I’m sure will be looking forward to greeting your new baby into the world. Sorry if this sounds harsh but living with an addict is hell.
Take care and good luck with the baby.
Dx.
