Fighting with my fiancé

My fiancé and I have never had a “proper” fight. One of us gets upset and we talk through it. Well today was my breaking point and I just started yelling at him for making me do all the work for the wedding. I’m the one trying to make things work and he keeps putting things off for the stupidest reasons. He literally told me one day that he wasn’t going to work on the invites because he didn’t want to and now we have to get them out in two days and he still won’t do them. It also has taken him up until me yelling at him to set up a day with his brother to try on suits which took less than five minutes. Months of telling him to do stuff and he hasn’t. I think me yelling at him has made him realize he needs to get his shit together if this is going to work.
