The sex toys

Angrily stomping after Lily, I arrived in my room to find her underneath my bed, pulling out a particular pink and purple shoe box. Sticking out from the box were all manners of toys, dildos, vibrators, lube, handcuffs, and more.

"Um, what the fuck do you think you're doing?" I come up from behind her and ask.

"Half this shit is mine, I bought them, so I'm taking them back." Lily pulled herself out from under the bed and dumped the contents onto my bed, examining each one and starting to sort them into piles.

"Oh, so first you sleep with someone behind my back, and now you're trying to take my only remaining source of pleasure. Jesus Christ, Lily when did you get so heartless?"

Lily snapped around, pausing her sorting. "I already told you, Christy. I apologized. It was a mistake, and I've done everything I could to make up for it."

"You did jack-shit!"

She ignored my comment and sighed. "I just want some of the things I bought, and then I can finally get the fuck out of your life. That's what both of us want, right?" And she turned around and let herself continue her business.

Now, while it was true that she did buy some of the toys, arguably they were a joint ownership type of deal. And as the insulted party here, I should get a say over the things I get to keep. Emotional harm and all that. So am I just going to let Lily take my favorite toys, or can I find a more... creative approach to the situation?
