In some fanfictions, Vegeta could be under the influence of some external force. Maybe an evil entity has convinced Vegeta that kidnapping Goku is the key to achieving ultimate power. Vegeta, being power - hungry as he is, falls for it and kidnaps Goku. But later, he realizes his mistake and has to make amends, which can lead to an interesting story arc of redemption and friendship building between the two Saiyans.
These fanfics are popular because the relationship between Vegeta and Bulma is so complex and interesting. Vegeta is a proud Saiyan warrior and Bulma is a brilliant Earthling scientist. Their different personalities and backgrounds create a lot of potential for drama and romance. Fans like to explore how they can overcome their differences and fall in love.
Maybe Bulma is too busy with her scientific research and family matters to be interested in fanfic about Vegeta. She has a lot on her plate, from taking care of Trunks to working on new inventions.

Well, Vegeta and Bulma are so popular in fanfiction mainly due to their contrasting personalities. Vegeta is this tough, proud Saiyan warrior, while Bulma is a brilliant and often sassy scientist.

Maybe in the fanfic, Vegeta did something unforgivable like betraying Bulma's trust or putting her in great danger while under the influence of the Majin transformation. For example, if he endangered their family or made a pact with the enemy that directly opposed Bulma's values.
Some exist because it adds drama to the relationship. Writers like to explore the complex emotions and conflicts that can arise between two very different characters like Vegeta and Bulma.
One reason could be to create a more independent storyline for Bulma. By having her avoid Vegeta, it allows the writer to focus on Bulma's own growth, her friendships with other characters, and her scientific achievements without the influence of her relationship with Vegeta. Also, it could be a way to introduce new and interesting plot twists. For example, how Vegeta would react to being avoided and what steps he might take to try and win her back or at least find out why she's avoiding him.
