Which type of conflict does della face in o. henry’s “the gift of the magi”?

I studied this story a little while back. The conflict that Della faces is the decisions she has to make to get a gift for her poor husband. In the story, it explains that her hair was the longest and most cared for in all of the lands, that even the queen would look poorer than her.
