Hi Icandothis,
That sounds really unsettling especially when there is no reason for him to be so close to your house. Sounds like he is doing it on purpose and to make you feel triggered. That sounds really scary, I hope you are okay and safe this evening. You have made progress I’m sure but seeing him out of the blue and unexpected is going to throw up some turmoil for you.
Not sure of your whole situation, but can you report it to the police, flag it up? I was told if I had any further contact to call the police and update it. Sounds like stalking behaviour to me.
Be safe x*x
