Name changed as I'm fairly certain P has been reading my mumsnet stuff.
Just had a huge row with my P, I was sitting on my laptop ordering our DD a new passport when he flew into a rage, snatched the computer and started saying that he would do it as I would make a mistake. Apparently I can't be trusted to do something as important as the above 
I have been with P for about 3 years and have DD 18 months together. He often comes out with things similar to the above situation and has a couple of times hit me (though he says only lightly but has never apologised and I have photos that I took at the time of a red hand print on my back.)
He never does anything around the house, though does work long weeks so I guess that is a form of excuse. Heck when he changes a nappy it requires a fanfare as its such a rare thing.
I feel so run down and like there is nothing left of me but I just can't see a way to leave him. We share the lease on a house (runs out in June) which I can neither walk out of or afford alone and my mum is our guarantor so can't risk it all falling to her.
I just feel so lost and have no idea where to turn or what to do
