just to vent

I'm sorry I usually never post stuff like this on here but here it goes: My husband came to pick me up from visiting my moms house. He then asked if I was hungry so I wanted del taco. As we drove to the window to pay his phone started ringing I told him: " your phone is ringing" he yelled at me and said :" it's none of your business " I looked at him like wtf. I've known him for 4 years and he has never talked to me like that. He then dropped me at home and said I'll be back later so I got out slammed his car door and said whatever. It just hurt me that he said that to me as him and I tell each other everything. I just wonder what he could be doing.... I am almost 20 weeks pregnant... and I'm just so emotional right now.... 😥 I don't know what to do or how to feel...
