move on, keep going forward
Amiga, você precisa superar o seu ex-namorado, bola pra frente!
Girl, you need to get over your ex-boyfriend, move on!
Bola pra frente ("ball forward") comes from football: when a team is losing or under pressure, the cry is to send the ball forward toward the opponents and keep the play going rather than dwell on what went wrong.
