Advice needed urgently please!!

I'm in a desperate situation here with no way out. Sorry for the long read!! Myself my husband and little girl were forced to move in with my in laws at the start of the year due to financial troubles. Fast forward to now we're in no better situation with money as husbands business didn't make any money and I'm now pregnant (26 weeks) with my second so if anything we're actually worse off 🥲😂 As I'm sure you can all appreciate, living with my mother in law has been unbearable and my mental health has suffered so much this year. Without going into things in depth she's a very over bearing person and I've missed all my babies firsts. The idea of staying here any longer is enough to make me want to give up entirely. We aren't able to live with anyone else. I basically forced my husband to get a salaried job as I was paying for everything and we wasn't making any progress. He earns 30k a year which is pennies that I know he resents me for. On top of that I've basically said we have to move out and attempt to make it on our own because I cannot be in this state of mind anymore especially with another baby on the way. He holds even more resentment towards me as he doesn't want to do it and doesn't "agree" with it but is "doing what I want" so what's the problem? Except I'm getting nothing but friction from him in every way. I get zero emotional support from him in any way and I feel so so alone. I'm really at a loss as to what to do as of course now I'm heavily pregnant with my second I feel like I've been coerced into this helplessness and I can't get myself out of this situation. I go round and round in my head and come back to the point that I'm stuck here with no way out with no support network from anyone. Any advice would be amazing please!!
