Does once a cheater, always a cheater really apply?

im currently interested in this guy. i just started to really hang out with him a month ago even though i have known of him for over two years. he is really nice and caring. one thing that strikes me is that he has been worried that he will hurt me. we are currently waiting on starting a relationship since we want to get to know each other a little better before. he has had a reputation of having with his friends girlfriends. it has happened three times all within the last year. he feels very guilty about it and it also seems that it is a pattern in his family. he is scared that he will do the same thing to me. but the thing is that he hasnt been in a relationship for over two years and i think it was more of him being jealous of what his friends had. he told me that he has never had what they had and all of his relationships had been very platonic, mainly just cuddling and talking, no . i can see that he is blessed to have me and i have already made a impression on him. seeing that he told me that he has no interest in anyone else as do i. frankly im not worried about him cheating on me because of how he acts around me and what he has said. he has also been hanging out with me more after i confronted him after my gut was telling me something was up because he was being a bit distant and i was only seeing him once a week. im just looking to hear some second opinions. this time its a bit different because i havent been worrying about him being interested in anyone else etc, frankly im also happy where i am right now. even though im not dating him. im very much interested in him but my past reactions/response are no more with this guy.
