What do I do?

The person I was “dating” went MIA and it didn’t hit me till one of my friends told me I was being played after the fact... he still has my jacket and I have two of his shirts. He gave me it’s been about two months, since I’ve asked for my jacket back and have been wanting to return his belongings. I asked him nicely once got no response. I asked him twice two months ago with a firmer attitude and all he had to say was “ yeah you’ll get it back” 🤨 still haven’t revived my jacket we haven’t spoken and I’m pretty hurt. I was a great fucken friend to this kid, I spoiled him and opened up to him about personal things. I thought he truly cared... I dunno what to do should I just let him keep the jacket even if it holds value to me and send his shit to him or give his belongings to his friend? I don’t feel like reaching out will do no good. He’s not who I thought he was. 🤷🏼‍♀️
