I Love My Daughter

My daughter who is in kindergarten just got her own room. She has always been in my room but she needed a room for herself and so did I. The boys are gone so finally a room was free. We've had fun decorating it and she loves sleeping in it but I ran into a problem. I can't sleep. I know it could be because she's always slept in the same room as me before but I think it's something more and I think I've got it figured out. We always put ourselves in between our children and danger. Wherever we go with our kids we unconsciously protect them by physically limiting access to them by outsiders and other possible threats. My daughter's new bedroom doesn't allow me to did this. In between our two rooms are two exterior doors. Those don't bother me much. Then there is another two exterior down a hallway past her room. Both of those doors do not have secure locks. So four exterior door surrounding her and I'm on the outside. Does this make sense? My other concern is there is a guy who blames me for getting him trouble with the law and for supporting his girlfriend whom he would beat on. He always thinks people are plotting against him and also blames me for getting him kicked out of the place he was staying. He showed up one day to talk with me to try and make me understand how he is the victim in all of his problems. I don't know why my opinion mattered to him. Anyway he has a warrant for his arrest and the police can't find him. Yet I'm finding on our property gates open and locks destroyed on doors.
Am I crazy or do I have good reason for concern? I'm fixing two of the doors today.
