I broke up with my boyfriend after 8 years now i want him back?

5 months ago i broke up with my boyfriend because i wasnt happy and needed time to myself. I moved out of his parents house and back in with my dad. For about 3 months he tryed so hard to get me back was always wanting to spend time together n really started changing for me coz we hardly did anything that was that main problem. I was totally not interested in gettting back with him at the time coz i needed to find myself, i still had feelings for him and cared about him heaps but just wanted to get out there n explore life. Anyways after about 3 or 4 months he suddenly gave up trying didn't call me as much and was just plain giving up coz i didn't want anything. Stupid me after those 3 months or wateva i have finally realised that he had changed and had been trying so hard and i gave him nothing now i regret what i did soooo bad and all i have been doing is crying because he said he can't commit to anyone at the moment we fight to much and he's sick of being pissed of every day and he can't handle it anymore, and i always get angry at him coz apparently he does things i use to get mad at when we where going out i.e: drinking. he said he let me do anything i wanted but he never had a life and coulden't do anything coz i use to get angry at him all the time. Im so confused as to why that wasn't a issue when he was trying to get back with me but now all ov a sudden he has just changed. I have now realised the pain i have put him through the last 5 months and i cannot stop crying and im just completely heart broken and cannot forgive myself for taking him back when he was trying. I feel like my whole world is comming to a end im just devistated and never knew how much he ment to me until now. Do you think he will ever come back after 8 years? does he need space? please help im so lost and confused.
