Stupid iPhone crashed

My iPhone crashed and I am getting a new one thanks to my dad who was nice enough to order and ship me a new one.
But I ended up losing all the screen shots of all the meaningful messages my fiancé had sent me. Like how much he loved me, how proud he was of me, how beautiful I was to him and how excited it was about the future together. All those are gone. And idk I’m just really sad about that.
