Well, a frequent theme in jealous friend stories is insecurity. The jealous friend usually has some insecurities within themselves that make them envious of their friend's situation. For instance, if a friend is more popular or has more success in a particular area. Another common aspect is the lack of communication. Often, the jealous friend doesn't express their feelings in a healthy way, which leads to misunderstandings and problems in the friendship. And there's also the theme of possessiveness, like when a friend feels like they 'own' the other person and gets jealous when that friend spends time with others.
One jealous friend story I know is about two girls, Anna and Beth. They were best friends. When Anna started dating a really popular guy in school, Beth became extremely jealous.

Well, in many Percy - related fanfictions, if we consider Grover as Annabeth's friend, he might be jealous of Percy because Percy often gets more attention or seems to be more in the spotlight.

One common behavior is making negative comments. For example, if you get something nice, a jealous friend might say it's not that great. Another behavior is trying to undermine your achievements.

One story is about two best friends, Tom and Jerry (not the cartoon characters). They met in college. Jerry was out as gay but Tom was still figuring himself out.

A big challenge is when the best friend has different beliefs or values regarding homosexuality. For instance, if the straight best friend comes from a very conservative family, they might struggle with fully accepting their gay friend at first. There could be internal conflicts.

One of my best friend critic stories was when my friend told me my new haircut didn't suit me at all. At first, I was a bit offended, but then I realized she was just being honest. It made me think twice before getting that style again.
