Hi
Peace4ME ... . great job in reclaiming your home
Without knowing your history I would give some general advice that applied to my situation... .
1/ Do not become involved in discussions about why this is happening... . it's past that now... . it will escalate the drama.
2/ Request his keys back... . even when you get them (or if you don't) change the locks! this is ESSENTIAL!
3/ Make sure EVERY possesion of his is removed from the property... . things are often "left" as an excuse for more contact at a later date.
4/ If you are close to your neighbours, inform them (when he has) that your ex has left the property for good, and has no right or need to be there... . and you'd like them to inform you if they witness him "loitering around".
5/ Smear campaigns can be minimized by having a friend or family member who is aware of the situation to be present at ALL times your ex is clearing his things... . and for a few days afterwards if needs be. Keep in regular contact with people you trust, that are local... . and report any "odd" goings on to them, no matter how small they seem.
6/ Stay focused on WHY this has to happen right now... . rather than the sadness of it happening.
I am not meaning to alarm you, I think you have every right to be sceptical about his behaviour, this is practical advice... . and you did ask!
A question... . why would he have to "start" to move out this weekend... . moving does not take long if you have the vehicle and the motivation to do so... . it sounds like it will be prolonged?... . Could you clarify?... .
