Husband threw a phone charger at me

We were arguing and i snapped at him. He then proceeded to throw his phone charger at me. Im pretty sure he threw it hard because the base and the cord seperated and flew off in seperate directions once it his the floor. Missed me completely, but was aimed at me. After i told him not to throw stuff at me, he only replies with "then dont snap at me". He later tried apologizing, but that turned into him getting mad at me because he says that i snap at him every day. We have a 1 year old that was in the room for all of this. What do i do?

Btw, i pay all the bills in this house.
