My domestic partner - we are unmarried - has maliciously destroyed a computer belonging to me (approx value £2000) following an argument. I don't want to respond in kind, but I want to send a signal that this is not acceptable behaviour.
If I report criminal damage to the local police, will this be taken seriously? And is a prosecution automatic or will I need to press charges? I don't actually want to end our relationship (we have young children) but I want this incident officially logged.
