i am so sorry for your whole situation with your partner just before you are to give birth. it sounds incredibly difficult and so hard to be left wondering what happened and what will happen now. i think if i were in your shoes i'd start planning a life without him, and if he ends up being stable and you feel comfortable taking him back then you can. i think if you put your life on hold and there is a long wait to resolve things it will be really hard on you and your little girl. when he told you he loved you and would be by the next day and then broke down or vanished or whatever tells me he probably isn't being honest with himself, or you, about what he really wants or is capable of.
