Guys, why is he trying to make me jealous?

Anonymous
the guy I am romantically involved with keeps mentioning how other girls always try to hit on him or that they ask for his number from other students (he's 20, and I'm 24 so he's still in uni) and he always says he's honest with me about it but everytime he mentions stuff like this it silently pushes me away cause I don't have time for someone trying to make me jealous.
