sooooo

soo my boyfriends last relationship was quite an abusive one by him and his girlfriend.. I would say he was more abused by his girlfriend also they where together for three years . But any ways here lately he's been talking about how he misses it and wishes he had that kind of relationship back and how he just wants and has the need to hit me or just something sometimes.. idk should I be worried ..? Could this turn into something more ? I mean I honestly don't ever think he would ever hurt me like that .. ever !
