I got a teacher fired for ual harment. will he come after me n how do i keep it a secret from gossipers?

just last week he was fired. most people knew he liked me, he lives 20 mins away from me-im scared he'll do something. and i got to an all girls school, so naturally if its a secret everyone knows. stuff like this spreads like wildfire in my school. how do i keep it on the low??
