am i gonna be a single mom?

he hasn't acted excited at all, he's distant when i try to show him baby clothes i bought, and he picked out a name for a dog quicker than he decided on a name for the baby.. i just feel like he isn't even excited at all. 

we have been together for two years. but, when i found out i was pregnant he convinced/bribed me to move out my apartment by telling me he would help me with whatever bills i had/costs to move out/my phone bill, ect. well 3 months later and he hasn't paid for a single thing for me, or the baby. his mom bought us a crib and i've been the one buying clothes with the little money i do have and help from my parents because my job made me quit because of my lifting restriction. i didn't want too but i had no choice, so i got on food stamps where i live and WIC and i use that for groceries for the both of us. my birthday was this month and he didn't get me anything. (he makes 3,000.00+ pay checks) i would spend my last dollar on him if i had too and he knows this and he can't even get me something for my birthday.. 

we got into an argument today and out of anger i said "why are you with me then?" his response was "well i guess i don't have much of a choice, do i?" 

i don't know how to tell my parents that me and  the father of my child aren't getting along .. and i don't have the money to get an apartment on my own because i'm not working. i'm terrified to be a single mom. i don't know what choices i have or who to even turn to about this.
