Welcome Bee. Addiction is a progressive disease and usually gets a lot worse before it gets better.
There comes a time when we have to decide whether the pain of leaving is any worse than the pain of staying...at least the first pain heals over time.
I am not sure how old your children are now but it is rarely a healthy environment, physically and emotionally, for children to grow up in.
I am glad you found us and hope that one day soon you can find your peace and take care of yourself and your girls.
Hugs
