My ex new partner has BPD diagnosis. She seems to be jealous of the children, although he rarely sees them. She thinks we are still together maybe? Suddenly want to be introduced to them tomorrow. I don't know what to think. She was at the house the other day when ex made rare appearance to see children and she tried to barge into the house and demanded he 'deletes her photos and number', She called the police as I didn't let her in - they didn't do anything. She has called the police at least 3 times in the last few months for the same level of incident.
