Hello. I am so sorry to hear what you are going through.
On a practical level, it’s impossible to comment on the police response without knowing all the details. I’m not even suggesting that you should give us all the details, as the chances are that there may not be anyone here qualified to help. Depending on the laws where you live and, crucially, your age when this took place, it may well be the case that the police do not think that a crime has taken place. If you were physically assaulted by this man, for example, that is a crime virtually everywhere. Likewise if you were a minor at any point during these events. However, many jurisdictions still do not have laws that adequately address situations of emotional abuse or abuse of a position of trust between adults. I would recommend that you contact a local advice or advocacy service that will be able to advise you about the specific laws where you live as they pertain to your particular circumstances. If you are in the US, you could contact RAINN, the National Domestic Violence Hotline, or Love is Respect. If you are in Ireland, you could contact Rape Crisis Help, Women’s Aid, Safe Ireland, etc. If you are somewhere else, I am sure you can find similar resources near you.
I am more surprised that the diocese did not take any action. For one thing, a priest simply should not be in a romantic relationship with anyone, let alone an abusive relationship that causes the other person trauma. If your diocesan bishop isn’t interested, you could contact the metropolitan archbishop (assuming your diocesan bishop isn’t a metropolitan archbishop himself) or the national bishops’ conference. Ultimately, you could seek intervention from the Congregation for the Clergy or Congregation for the Doctrine of the Faith, which has jurisdiction in cases of clergy sexual abuse.
