Am i overthinking this?

me and my boyfriend have been dating for about two months now and we dated before so we know each other really well. he is used to only having long relationships and i am not at all and before we started dating he was in a long relationship and so he stays comited to girls he dates. he hasnt broken up with anyone ever cause he gets to scared. and right now i know he likes me alot and i like him alot but do u think if he usually has long relationships that he would want one with me also? cause i really like him and sometimes i feel like im boring him so how can i keep my guy interested and just what do u think of my sitchuation
