Does he love me?.Why is he acting this way?

I am into an online relationship with a guy since,5 yrs.He proposed me,even without seeing me.I too loved him.Later,after sometime,he said that,it's not love,he is infatuated.I decided to quit the relationship but,now asks me not to leave me.We met 6months back.What is there in his mind?.Does he love me or lying?
