Annoyed and angry

My so is amazing and wonderful... Honestly if I saw us on the street I would hate us. We're so cute sometimes, but sometimes he's a bigger girl then I am. Like just now. I worked morning and he's working nights... I missed his call by 30 sec... Not kidding, when I called him back he ignored my first call.. Called again and answered all angry.."why didn't you answer?? I called you twice?!" I said I'm sorry honey I didn't hear it. I'm listening to music... He got butt hurt, we talked for a min and then had to go. Does anyone else have a sensitive so? How do you deal with feelings like that?
