I think i'm still in love with my ex.what should i do?

i was with this guy for about 4 years. he's a great guy. but we were like from 2 different worlds. he's the 'angel',me the 'devil'. the whole time i was with him, i became someone different. i was a better person and many people think the same way bout me too. he was loved by my family and friends. but towards the end of our relationship, he moved to another state, about 8hours journey from mine. we saw each other lesser,like twice a year. i started to feel bored and i suddenly realized that i missed the real me. finally, i decided to put an end to our relationship. it was really hard and i spent a lot of time thinking whether i was doing the right thing. and i feel like my life has been kind of chaotic after that. it's been more than a year now and i still finding myself missing him eventhough when i was with other guys. i dated 2 guys after him, those i thought who are more like me, totally opposite of him, only to find them to be total pain in the *** jerks. him on the other side, has not dated anyone after me, and even said he would wait for me. now i think the real problem is i'm still in love with him, but i think it would be real bad if i wanted to go back to him after what i've done. plus, i'm sure he would be heartbroken again if he knew i've actually seen other guys after him. should i tell him the truth, that i still love him? should i tell him the truth, about the real me and about the guys i've been with after him?
