Would you stay?

So, I’m currently 7 months pregnant by my bf… and lost my job but am supposed to start a new one next week. I won’t know how to get there being that my phones off, and am currently struggling really bad

I asked my bf if he could pay my phone bill which is $50 and he said he will, but hasn’t and I have to be at work soon. I don’t have anyone else to really rely on and am in desperate need to get back to work. He hasn’t provided a thing for baby and I’m doing all I can but I’m so stressed out idk what else to do… he’s so unreliable and inconsistent he’ll go hours a day without replying to my text but gets upset if I did the same. Would you stick around or should I just leave and prepare being a single mom? I need advice
