"i want to leave my partner but have no where to go,, i live with him and his 2 sons and its horriable here,, he wont let me go out and when he dose he say im shagging around,,he puts me down, dosent listen and some times i want to die. what should i do"

No where to go is lame, sorry. There are thousands of women who have small children and yet LEAVE, and you don't even mention children of your own. Do your legs walk? You go to a shelter, for starters, and they will help from there.
