Am I wrong for being up set ?

So today started as an ok day I showered did my make up and dresses nicely. Well I am 20 and I am working on getting my license so my cousin takes me driving. Well today I had shorts on because it's hot as fuck out side. Well I have not left the house in shorts since I was 15. Well i just drove to the gas station that is less then 5 minutes away from my house. Well my fiance got mad and said your wearing thos and when I said what he got mad and said nothing. Then I stood up and he said your ass is hanging out the back of them. They go down to my finger tips 😐. So I said no it's not and he said what ever so then I left he sent me a text asking for me to get him a Mountain Dew and I didn't reply right away so then he texts my best friend who didn't know I was driving and had her call me to ask me to get him a mountain dew 🤬 I am not mad at her but at him. Then I get there and I call him and I say do you want it or not and he was on the phone with me for 5 minutes..... saying he didn't know he didn't care and also asking about a phone charger for my little cousins phone it was $20🙃 😒 then I get it and get home and he is happy then he takes a drink brings it in and sets it down and goes to the bedroom as he passes me in the hall he says you can have it it has fucking ice in it ( he doesn't get ice in his drinks ) I forgot when I was on the phone with him that was when I was getting it. And then he started asking me what took me so fucking long 🤦‍♀️. I was gone less then 20 minutes because I had to swing by my cousins house who is also only 5 minutes away so the time in the station the time to drive over to my cousins place then the drive back home. But it took me to long 😡

Am I wrong for being up set ? I have not worn shorts out side of my house since I was 15 I always changed back in to jeans before I left. Now i start to get some type of confidence and it's wrong 😖
