I’m so upset

I am 35 weeks. My husband refused to get the flu shot until today. But did it after about 2 days of us not talking. Today i asked him to please speak to his parents about getting it as well and he refused and yelled and just left the house. I am so upset about this. He thinks I’m blowing things out of proportion but I think that it is so important they get it. He won’t even talk to them about it i don’t understand. I can’t stop crying and feel so unsupported.
