Extremely stressed and sad

Basically my husband is shutting me out. We have 8 weeks left till our little girl arrives and a 2 year old son. We have our own business but right now in the winter it gets a bit slow. He also is a barber and will cut hair on friday and Saturdays. We are behind on bills and owe a lot of money to credit cards ect. We basically got a lot of stuff on credit in the spring /summer when we were doing good and recently moved into a house that is perfect but we pay more to rent obviously. In total we pay about 5k monthly in Bill's, rent, car, insurance ect. And now that it's slow we aren't making as much and he literally does not know how to handle it. He hardly talks to me and when he does he is so mean. Yesterday we were arguing and I got so worked up from crying g that I started having some intense Braxton hicks. It was painful and we were driving home and he LITERALLY just drove. No words. No touching...nothing. it broke my heart. We got home and I showered myself to try and relax and he was playing with our son and getting him ready for bed. I laid down and he was still putting our son to sleep...he didnt come into our room till about 10pm ...(2 hours later) cause he was just on whatsapp talking to his friend that he made a song with (he is also a "rapper/singer" from his hometown in dominican rep.) So....those are a few examples. I understand he is stressed and wants to provide for us but he is literally treating me like garbage. I dont know what to do I just want to run away but I cant I have no where to go. No family to help. I'm also a full time college student studying nursing... I just feel like my marriage is broken. 😪 sorry this was long my hormones dont let me just brush this off unfortunately
