So glad you have supportive friends, and that you've got rid of him and got your card back.
DO NOT weaken no matter how much he cries and apologises and promises it will never, never happen again, because it will
DO go to the police and make a report while your injuries are still visible (tomorrow would be good, as it will have allowed any bruising to start to become apparent).
Remember that men like this DON'T change - if they aren't stopped it gives them confidence - they begin to think that they are untouchable and that they can treat you as badly as they want and there ill be no comeback. This is how every attack becomes more and more serious, and attacks become more and more frequent.
He may come round with flowers and choices - ignore him. Remember that an abuser isn't an abuser every minute of the day - if he was it would beast to leave him and avoid him. It is the ability to charm and be plausible coupled with unpredictability and need to control that makes him so dangerous.
He is a danger not just to you but also to other women. If you report him, you are helping yourself and the next woman, because his behaviour will been record when she goes in to the police with her injuries (and there will be a next woman - have no illusions about that).
On average, a woman in an abusive relationship leaves her partner SEVEN times before she finally realises that she MUST get away and stay away. This is your first time - bring down that average. Make it your first, and last - don't ever let him back.
