love me not

I am in this relationship and have been for 2 years i have a daughter with this man and he treats me like crap most of the time. If i see someone in my position i would tell them to get out, forget him you deserve better, but as it is me i cant understand why i am still here. i really dont know what to do anymore, it like when he says sorry it makes it ok for a while but it doesn't last long he never hurts me just verbal assault and the kids are none the wiser.

just so tired of thinking if what i have done will upset him or if i am going to get yelled at.
Example of all this is i have been really sick lately and have had to have lots of blood tests and xrays and things and he doesnt have a job so he is always at home, i am always doing everything and he sits in the nice lounge i bought out of my wage and he doesnt move all day, i mean he is 21 for goodness sake, he swears around the kids and has no compassion towards anyone.

i said that i was scared that the cancer was coming back and he just so you be ok and i was crying hoping for a hug or a least a conversation about the possibilities and i got NOTHING from him i was devastated!!!!!!!!!!!

Question to you all what should i do???????
