Does my ex like me again or something?!?

See now this could be two things, he may want to get the really closeness of you two back seeing as your best friends, or yeah he does want you back but this is a bad thing for boys to do it but still... he wants to know if you would take him back because if he were to break up with his girlfriend now and then you say no, he wouldn't have anything now would he so if you want to be with him then let him now some way or another.
