He is a slimy fuckwit of the highest order and you are better off without him. I doubt you see that now and it doesn't really help you with your current situation.
Where are you now?
Is there somewhere you can go?
Council/womens aid may be able to help if not.
Old friends you have not seen for a while may well be more supportive than you think, especially if you tell them what has happened.
You need your stuff, if he won't let you get it then call the police
When none of his bills get paid he will soon realise who needs to do the growing up
Poor you, and your poor dd too
Sorry, don't have any more constructive advice
