Trying to not be sad...

My boyfriend and I have been together for 5 years. In two weeks we are taking a vacation to the beach and I was hoping he might propose then (he’s been hinting at it for a long time). . Well, he told me today that I shouldn’t get my hopes up because the ring won’t be here in time because of Covid-19. I know it’s not his fault, but I was just really hoping it would happen then because we don’t go on many vacations and it would be perfect time since we would be with his family. We live in the middle of no where in Missouri so there is nothing here. I guess it just seems selfish of me, but I can’t help to be sad about it. He said that he had something different planned, but I can’t see us doing anything else especially when we live in a boring place..
