Can someone give me some advice please

I’m wanting to separate from my husband but I really don’t know where to start. I have a 2 year old and another on the way and I’m not working because I got made redundant. We have limited communication, have for a while now, constantly arguing and it’s just not a comfortable way to live, I don’t feel any love there anymore. I’m worried because I’m not working and can’t get a job with being pregnant. I have parents nearby who I could live with but obviously don’t want to put them out. My husband refuses to leave the family home so basically I need to pack up and get out with my daughter if I’m wanting to go. Anyone that has been in my situation, do you have any advice?
