Should i wait for him? or should i go get him back? or should i just forget him and move on?

there was this guy i had met a few months back throught one of our common friends. she wanted to set us up but both of us said no as we both thought that set ups never work out and both of us closed the chapter. then after 2 months or so we again started talking on my bday as he had wished me thru a text msg. And dats how we started txting each other everyday. In those talking how we boht fell for each other, we both didnt realise....v even met twice throughtout this process. and both the times he treated me really well. The only thing that was very different between us was that he was a hi-shot and a very hi profile person....always clubbing and partying and i am a very simple and homely girl. Then almost 3 weeks back....he got drunk and gave me a call...and confessed all his feelings for me, that he realy likes me and stuff....but he was drunk so i didnt want to confess anything from my side...so i told him to go and sleep and talk to me later. and den from the very next day his attitude changed....just a single call in a whole day and dats it...and den he came to me the next day and told me that he wants a break from all this and stuff. i knew something was wrong...so i told him that things had got preety weird between 2 of us...we were more den frnds and less den couples. so we decided to meet up and talk about it...but then we cldnt meet up and talk...so we spoke on the phone...he wanted to make me stop talking to him, cuz he thought that he would just hurt me...as his drinking always used to irritate me..and he didnt want to get into a relationship and hurt me anymore....i didnt know what to do..so i ended up even breaking the friendship because i was really hurt by the way he way behaved. then after a few days v spoke again...and cleared out everything...and ended up being frnds again...but my behaviour towards him was really rude...and dat was the last time we spoke which was 2 weeks back.what he did was for my good and i know for sure that he isnt a player....he feels that he lost his ex(they had dated for 3yrs) because of his drinking and his some habits. and he feels if we date he is going to **** it up with me also.....i do have a problem with his drinking...and dats the reason i didnt stop him from walking away. but i do feel bad for him more den i feel bad for myself, and i really dont know what to do...at times i feel like calling him up and talking to him and saying him sorry for the way i took him wrong...but that looks despoish...so its best i dont. but this guiltiness is just killing me..and i do care for him...so i really dont noe what to do...should i wait for him?
