Why does Ex want to know if i Miss him

Me and my ex split up a week ago , he said he wanted a break and i told him to take a break for good.We exchanged a few horrible texts and left it at that. 4 days later i emailed him to just say i was sorry for what i said and i agreed we should take a break since then he has started to email text and speak to me on msn. He has asked if i want him and miss him. He keeps saying that he doesnt want me to meet anyone else and it bothers him .Before this he said he didnt want to call it a day it was the way i was acting that caused it. i'm all confused as why would he want to know these things if he wanted to call it a day. I still love him and i do want to get back together with him but i cant keep letting him do this and then going back to him straight away.
He admitted last night he misses me abit but he's the type that never says out right how he really feels as he is stubborn and too proud.

A male opinion is very much appreciated
