Depress House Wife

I have been with my fiancee for a year and two months, he have two kids and i have none. in the beginning of the relationship it was perfect, we spend lots of family time together, had lots of fun enjoying each other. he was supporting the family financially, five months later, he lost his job, i started doing every thing for my family, all the bills everything.. that time we were our happiest.
Now things beging turning, im out of money i spent every last dime on him and the kids. he recently got a job and all of a sudden i became the enemy.
he told me that i wamt from him is money, he treat me like im is helper, now i have no social life, all my friends hate me because of him.. he buy the kids computers, gifts, every thing they want, and all i hear every time i am too needy. if i look sad he never ask if im ok.
i just feel trapped, unwanted, depressed, sad, i want to leave but i cant, i gave this man every thing i had, everyday i sped at least one hour locked away and cry...
