pregnant & dealing with stress

Thank you for all your msgs. My parents have taken me home cause it was getting too much. The drinking didnt stop and me getting stressed out was increasing day by day. He drinks because he is stressed and I understand. Work can be hard and having a baby can be scary for anyone but for his case it is more stress being given by his side of the family... his mum, dad etc. I have tried many times to tell him to tune them out but he cant. We do not live with them but somehow as a woman it feels like his family does not wish to let him go... When I try to confide in his mum about his drinking.. she blames me instead and says I should accept him for who he is and that men are men..🤷🏽‍♀️ His father for some reason has never approved of me. So I dont speak to him. Recently he has been saying sorry to my parents and I but the drinking has not stopped and the blaming and scolding has not as well. I am definitely thinking about raising our baby on my own cause I can't deal with him anymore. It is heartbreaking and so stressful and I just want the baby and I to be ok... Is it wrong that I am thinking of raising our baby on my own?
