welcome Rose. so very sorry for the events that brought you here. what a sudden scary change in your life!
your husband made a seriously bad decision to use again, followed with more bad decisions that landed him in the hospital. what was he thinking? one thing...getting high. probably thought he could "get away with it since mama wasn't home." medical treatment can help get him detoxed and stable, after that he will have some more decisions to make. hopefully good ones.
thinking of you and your little girl. do what you think is BEST for you. read around here.....lots of good stuff.
