If he follows you... then you can do this... he can just let you go and you MUST leave the system... if he decides to follow you instead.. you are "being chased" and you can re-engage with everything.
Quote:5.6 If a player engages cruise engine or docks during a PvP fight, this player is considered fleeing. The fleeing player must leave and may not re-enter the system where the fight took place with any of the characters on his/her account(s) while the enemy (player or players involved in the fight) remains in the system, but no more than 4 hours.
However, the fleeing player can re-engage at will if chased.
