Am a regular poster. I need some perspective and a handhold please. I will try not to dripfeed.
This morning I came downstairs with 11mo and found dp asleep on the sofa drunk/hungover at 7am (a regular enough occurrence). A blinding row ensued when he told me he wouldn't be coming to the hospital apt for her this morning as he would be working (read in bed hungover) and she then emptied the beer he'd left all over the floor and herself.
He accused me of being unreasonable as I've had 'a year long holiday' of maternity leave. For info, we have no family close by for support and DD is a terrible sleeper. I'm also unreasonable as he reckons I'm unappreciative as he thinks he has provided for us all year (he hasn't, I have continued to pay half the bills despite not earning an income). When I disputed this he left the room not before squaring up to my face saying we'd have to have a talk later.
DD crawled after him into the kitchen and when I followed to get her he went berserk screaming at me to get out. He picked up the high chair and came at me with it, all the time screaming 
I'm numb to be honest. This behaviour isn't uncommon, he has thrown stuff at the walls/broken things in temper before. When he's not working or working into the night, he goes to the pub or he's in bed because he's stayed up late or is hungover. I don't get any support looking after DD. I never get to go out to do anything in the evenings. I do every nappy, bath, meal, doctor/hospital appointment. I feel so resentful but I mostly feel so sad for her.
He is now going to blame me saying I provoked him into this. He never accepts responsibility for anything. I don't know what to do, I have no family close by. Please be kind MN, I'm feeling very vulnerable.
