Complicated Boy Situation?

Well he's keeping his options open. You 2 must be close if he told you that and u told him u like him. So he might just be doing this cuz he knows u like him so he's being nice and flirty. And talk about something new that happened in ur life or say something like "oh, that reminds me of the time blah blah" That should get the conversation going. And talk bout past crushes and stuff if he flirts more.
