Trying not to act like a stalker..please help?

Myself & my boyfriend just got back together on Thursday which I am extremely happy about .we had broken up a month ago to give each other a bit of space as we wer arguing alot ...But we sat down& talked over everything we both really missed each other...So here we are now back together. We agreed to take it slow in the beginning...But the problem is I am actually a very insecure person as a result of some childhood abuse...I have explained this to him but he too was from a similar background but is not effected in the same ways as I was...My problem is that I really want to be with him but I don't want to be too over needy as this is not attractive in either ! What im asking here is? Do people know of ways of building up my self esteem loose those insecurities he was very attentive in the beginning but with all relationships things calm down a bit obviously he wudn't text me the way he use to..(The problem is I need that attention or I feel he isn't bothered) how can I over come this?
