What happened? Description:

A fake middle man or third party scammer
I am a designer, and I sell designs and animations. Last month, my client (https://steamcommunity.com/profiles/76561198802122662) bought a steam artwork from me. He paid with a steam item, StatTrak™ AWP | Man-o'-war (https://steamcommunity.com/market/listings/730/StatTrak™ AWP | Man-o'-war (Minimal Wear))
Today, I was trying to sell my StatTrak™ AWP | Man-o'-war. My friend said to advertise on this place -> https://www.facebook.com/groups/1777474672499777/about
I tried to join, but it was waiting for approval, then I asked my friend who sent me the group link, to help me advertising my StatTrak™ AWP | Man-o'-war there
A view minutes later, a buyer came. He chatted my friend, and my friend tole him to chat me (cause I'm the seller)
I talked to him, he was so annoying, we just met and he said me "fool" like wtf
We talked a bit, and he asked for a middleman/third party. I agreed and he invited the middleman/third party to our chat
The buyer was so pushing me to done the transaction quickly. They even said I'm trying to scam him
I sent the item to the fake middleman/third party. Then he (the middleman) told me to give him my account as a verification of his rule. I refused, then I asked back my item, but he refused. He said he is trusted and the owner of Adicanger, Bitcoin, and the login is just for checking. Then short story, I gave him my account access (I have changed my email and password, also steam guard is on, and steam support to logout all devices is opened, in case if anything happened). He said he cant access, that I didn't see my steam guard, I gave him codes for my other steam account. He said I'm playing around with him. Then I just realized I gave wrong code.
After that, I gave him the right code, he said auto logout. Every time he said so.
It's just for checking right? He also said it will be quick
After that, my transaction isn't done and my item has not back.
I checked his inventory, my item has gone
