How to show?

Orc • You and me baby ain`t nothing but mammals, So let`s do it like they do on the discovery cha
So my fiancée and I have been together for five years, we've been through so much in such a short time, and we are currently planning our wedding. Today I got so stressed out I yelled at him "This is a huge mistake f*** this C***." I feel so horrible for saying that and apologized and told him what was really bothering me and he said he forgave me and we made up and have had a great night with family drinking and dancing together, but I want to find a way to really show him just how sorry I am and just how much he means to me. Any suggestions?
