Am I wrong?

Whenever we go out he dances with a lot of different girls I get jealous I tell him and he doesn't stop yesterday it got out of control I hit him he broke up with me first time I disrespect him by hitting him his never hit me or anything like what I did to him 😳 I know I'm wrong for hitting him.  Am I wrong to get jealous about him dancing around or letting other females dance on him? Idk what to do😢😢😢😢
