Some really good advice but could I also suggest talking to Victim Support if you have a local scheme, they can be very helpful for not only talking things through with but often they can advise on home security options.
While I have every sympathy with those who are mentally unwell, it's also really important to remember your own safety and wellbeing too - it's interesting that this person only appears to target women!
Stay safe
