Well done OP. You have seen through him- keep seeing him that way. You're already sounding stronger in yourself. If he turns up at the door again, just call the police straight away. Don't answer the door, obviously, well done for not doing that.
Proper channels such as the police or SS can provide real support to help you be prepared if he shows up again.
@youvegottenminuteslynn Maybe for some people, many others find them hell rather than supportive. They often traumatize women themselves.
My friend was in an abusive relationship, she's a decent woman, a CPN, she just happened to be involved with the wrong guy, it happens to us all/a lot of us. SS and the police saw her as a bad guy, took her baby off her, and now she hasn't seen her boy who's just turned 2, for 18 months, and probably won't be allowed to see him again until he's 18 years old. She's going to lose her job over it too. There's a lot of misogyny and personal bias in the system and how it makes its decisions. In the mean time, drug addicts and people with chaotic lives get their kids back.
@LanaLielaLie I'm not saying don't call the police if he turns up, but I personally wouldn't make them or SS aware anything's going on until that time.
