Jonathan confessed then got rejected by you because of two reasons: 1.) younger man aren't your type and 2.) you think of him as a child or little brother. Jonathan thinks it's crazy that you think that way. (He understands reason 1.) tho.)

Currently, at the party he got tad bit jealous when you are clingy with Jackson, his older brother so he decides to be clingy with you. He wanted to show you he was jealous...
