HELP!!! y am i an unoffical girl..guy advice repost?

i have this guy whom i been unofficially dating for 4months now.i got tired of being his unofficial girl friend even thought he treated me very well.i was kind of suspect because y wouldn't he want to date? we had a few times but that didn't stop our relationships improvements.then one day i asked for more which he didn't give to me,so i asked again if we could make us official.i dnt knew why but one day he kept calling and he knew i was going to be busy all day.so i told him.the next day he calls me and tells me he wants "us"to be over.devastated i just move on somewhat.but for some reason he called me ever day and text me everyday.i answered.i still have feelings for him and want to get back together.while we were broken up i tell him not to call me because he made me mad. which then he didn't call, started to miss him so i told him. he says he misses me to.he cares. but it seems we have a problem.im willing to work out everything...i get mad because he doesn't want to make us official and he doesn't understand..lately we haven't talked about that subject..but i do know one thing he has been hurt before and i so have i .i also know that he is really quit and doesn't express his feeling thru words.he thinks things thru allot and rarely speaks what he feels its like he is in a restricted bubble..wat to do about this?? and we have talked previously but it seems all he does is listen and not put in his 2Sense..its like talking to a wall that will think and change for u...i want to knew wat he wants too!!!
