I think he Still feels something for me?

My ex andi were together for 11 months, we have been split up since the end of september. I guess he was not sure of how he felt about me in the beginning stage of our breakup because he didnt say that he didnt love me anymore until about a month ago. We broke up because i was having alot of arguments with him over nothing. And one day he said the next time idid it then thats it wed be over. So being the idiot i am, it happened again and i had to leave, he cried the day i left and we continued to text after that. Well he was crazy for me and fell in love with me, and he was also my first love. I was just too immature, insecure and b*tchy to be with him. He gave me a couple diff reasons why we couldnt be together these past 2 months. But i dont believe he doesnt love me anymore, maybe hes hurt and all but i dont think he fell out of love with me. Well these 2 months ive been calling texting him like crazy at times because i really dont want to lose him. I have stopped finally and we are still talking, he still wants to have with me. ect. The last i saw him (like 3 weeks ago he had my pic in his wallet), hes told me that im a great girl i just need to mature, when i would get emotional when i saw him, he would say "and by acting this way u want to show me you wanna be with me?" He told me he would always keep a good memory but thats all in his heart a set place. The last time i txtd him like crazy he said "why would i get back with u acting like this so crazy" so what should i do? Of course iwant him back, it wont happen rite away i know, but what do i do from here? Thanks everyone. He is not a bad guy that would use a girl or anything. And so that kind of sends me the message he still feels SOMETHING for me, because he knows i still feel the same about him.
