I get married in August. Here is my rough draft of vows!

Georgie

im pretty unsure about most things in my life, but there is one thing I am sure of and thst is my love for you.

i cant promise that i wont get angry,

i cant promise i wont have bad days,

i cant promise that i will always be kind,

but i can promise you this,

i promise to love you until my last living day,

i promise to be proud of all your accomplishments in life, no matter how small they may seem,

i promise to celebrate the great days and hold your hand through the bad and,

i promise you will never face anything alone,

you are my world, my stars, my universe,

you are my best friend and one true love,

you have helped me become the person i am today and i know, because of you, i will be a better person tomorrow that i am today,

words cant describe how much i love you, so let us grow old together and allow me to show you how much i do.

I'm unsure if they're okay, should I add more, take away some?
