Is it normal for a relationship to end and the girl still get rights to your stuff?

So we still had 3-4 months on our lease and she wanted to go about business as usual and I was like no cause she had essentially already divided living spaces of the apartment. She still wanted to use my tv’s, speakers, cameras and I would get upset because once a relationship ends that essentially it. When i was in a relationship with her there wasn’t a single thing I bought that she didn’t have access to I even bought things often with the relationship in mind. This turned into another trauma element of the breakup because then after I got upset with her using my stuff still after the breakup she ran to her friends, our mutual friends and her family and was getting them to bash me saying I was being petty and I was like how and confused in what world can you you break up with someone and still use their stuff as if you are still a couple.
