OP you have made a statement to the Gardai. Do they not have to act up on it? Can they give you something in writing. We have a man up for assaulting his partner, who has been recording another female, who seems vulnerable (therapist) and people don't see a pattern here. If he thinks he can get away with things it may esculate. The OP did the right thing complaining to the Gardai, if it were only the recording without the assault case I too would have said let it go. Get it documented by the Gadai and forward that to the ex girlfriends solicitor.
