My ex bf still wears my bracelet?

Me and my ex have been on and off VERY good friends since we were freshmen. Anyways we started dating May 31st of this year and around that time he took my "I love Boobies" bracelet that I constantly always wore. I guess it was like so he could wear something of mine. June 19th he broke up with me saying "he felt weird" But whenever I see him, he's still wearing MY bracelet? What's with that?
