My Girl's a Fourth Degree Black Belt in Me

My girlfriend is a fourth degree black belt and it's made me terrified of her. She's constantly trying to fight me, and now that she can defend herself, it's harder for me to catch her. Even though she's a teacher now, she still tries to fight me. I still have some control when she comes to my place, but honesty doesn't exist in our relationship. Routine is what keeps us attached.
