r/Relationships; Disappointing Engagement Ring and A Weird Work Friend

Today we go into r/Relationships for a couple of posts asking for advice. In the first post, OP just got engaged and isn't too happy about her engagement ring. They talked pretty extensively about what she would like and she gave him options as well. He ended up choosing everything she said she would never want, from the color of gold to the cut of the stone. What do you think, should she approach her fiance or not? The second post is about a friendship. A work friendship to be exact, one that has become a bit weird. OP has hung out with this work friend only a time or two outside of the office. The office friend seems to think they have a deeper friendship than they do. OP hasn't been feeling very social lately and it seems as though the friend is offended that OP just wants some alone time at the moment, and won't give her a for sure date for a movie night. She has become much more aggressive about it lately and OP needs to address it somehow, how do you think she should go about it?
