It's unclear what you mean by "miss a date," do you mean miss a day of friendship/marriage points? Also, why are you not able to upgrade your axe? Can you please provide some context about what it was you were trying to accomplish, why you were trying to accomplish it, and describe what exactly went wrong during that (with details)?
Also, the WT language is a little strong given this is a
PG-13 family forum.
This page talks about dating:
In singleplayer mode, Marriage is possible only with a villager who is marked as "single" in the Social tab.

This page has info about friendship/marriage points "decay" if you were to miss a day of friendship/marriage points (it slows you down a little):
Friendship can be earned with Pelican Town's villagers. As friendships deepen, the villagers' dialogue lines become more friendly, cut-scenes called heart events occur, villagers are more likely to send gifts in the mail, and marriage is possible with one of the datable villagers.

No idea what not being able to upgrade your axe or has to do with dating, you'll need to elaborate. Bookmarking the wiki can be helpful to answer questions, since it is searchable. The relevant pages will also show up in Google search If you include "stardew valley" in the Google search. So for example "stardew valley dating" would turn up the marriage page, which also links to the friendship page that has the decay points.
