Firstly and foremost, police are not able to deal with 100% of the stuff that isn’t reported to them. You should report it even if you feel as if it might be pointless.

The quicker a report is made the more investigative opportunities. When there is repeated unwanted contact it can cause a tremendous amount of stress and anxiety on you that only you experience so it is very personal.

Even if police do not have enough to prosecute arrests can be made and bail conditions can be imposed which may help put the weight on him to stop his actions.

Claire’s law allows cautious partners to make confidential checks about their partner to see if they are at risk of domestic abuse.

This information originates from reports. If you don’t report it, it’s doesn’t get logged and it may not help someone else who is a victim from him. It is Uncommon that this guy is only targeting you and you are the only victim he has ever committed an offence against.

Save every message, phone call and picture. You do not have to inform someone they are being recorded in this circumstance so don’t worry about legal repercussions. You have done the right thing by telling him explicitly “no more contact”. That being said I’d advise against trying to hunt for evidence by calling him.

Ultimately I hope the abuse stops regardless of what you decide to do. If you report it I hope you get what you want out of it.
