Rolling adequate

Been training at a small Bjj gym for a little over a year

recently i haven’t been going because one of the members (white belt) goes to hard, cranks heels hooks, usually just cranks my neck in a head and arm instead of trying to finish it properly, piratic so you’ll get hit and hair pulled. He’s been talked to…

It became especially bad when i won a gold medal at a tournament, he made it very obvious he wasnt going to lose in any aspect on the mat with me after that.

He’s also always injured so rolling against him almost always goes wrong because he gets a ouchie.

Getting sick of it, it’s hard to avoid someone in a small gym. please give me advice maybe dirty things to do or annoying things during rolling.
