I don't know what to do

Chelsea

my fiance wants to leave to get us some money from his cousin i dont like or trust that side of the family, and he has to take the bus to get it since our car is down, I told him no and now he's throwing a fit saying I treat him like a kid. I just found out I was pregnant and have a young son and I'm not feeling good. should I let him go or stick to my guns. I haven't told my family I'm pregnant now he's threatening to tell them.
