he paid me

Ok so yesterday I wrote that my ex narc was going to meet me to give me the money he owes me. I told him not to worry about it I did not need the money. He insisted. Of Course it was supposed to be 200 dollars. I also had things I wanted to give him back, and some things were for his son. So I met him at a gas station today and he quickly gave me 100.00! of course I didn't get the other 100! Whatever! don't need it. Of course he had my Exxon card and key to my house. He did give me those also. I told him I have his things in the back of my car and he jumped in his work truck and said "I will get them later"? What? I thought this was the end! give everything back and be done. After all he text me nasty ugly crap today so I thought he would want his stuff and get the hell out. So freakin crazy. Is he trying to still have ties with me? I should just burn everything and give his ex wife his son's stuff back!!
