Ladies I need some advice

So me and my ex fiancé broke up in November and we tried to remain friends but alas she’s psycho and it didn’t work.

However, a few years ago I brought a PS4 for us at home, which I let her have at her mums when I kicked her out after a few weeks of guilt tripping that she was bored and lonely on the pretence we would remain friends and I could one day have it back.

What can I do to have this returned? I’ve given her so much over the last 3 years I feel like this is the final straw for me and to make matters worse she’s actively going out her way to cause me grief on a daily basis.

Any ideas? I miss my unfinished games and ability to stream whatever I want on the tv 📺
