Some men have these behaviours; they need to speak to you, they need to text you, they need to meet you, need to use your toilet or anything.
All of this is largely because they can’t stand not make an impression of some kind. If they can’t do that, or upset their ex or the kids by proxy, then they get worse.
This behaviour does vary, but it’s on a scale. It’s however self centred and may actually be harassment. Harassment isn’t necessarily domestic abuse or violence legally. But it can be a crime if you tell someone to leave you alone and they don’t.
