Simply because he is an unneutered buck, he will have pretty strong hormonal urges. Does tend to be sexually mature a few months later, so she might soon start to fight back, depending on her personality as well. It might settle down a bit when he turns into an adult (a year and older than that) but if you do not want your girl to be harassed and risking any more injury, or even becoming pregnant(if she perhaps hasn't already from the buck annoying her) it is best for you to find a way to keep those two apart for good.
I have no good ideas on how to make sure that the doors wouldn't be left open by your family constantly, as my own bucks had a whole other room in between them (basically a double set of doors)
Also, one of the boys had a cross-section with another door of a room, and since we needed the airflow, we took coated rodent mesh and stuck it on instead of a door(which we could then leave open), BUT it wouldn't really work in an area that is under constant traffic.
Another thing that helps greatly in terms of the agressor bunny boy is spaying the doe and neutering the buck, then keeping them totally apart for two months(hastening that period has led to no good, i can tell you first-hand experience with how my boys failed bonding because we were rushed) and after that attempting to bond. There is a lot of information avaliable on rabbit bonding already, and the plentiful benefits of desexing rabbits.
With all that being said, i am sorry to say that i won't be able to help you with the door problem. It is impossible to chase after family and close the door every single time they decided to leave it open. Have they not seen how the rabbits fight when the doors left open? Or do they just deem it normal?
