well mischa, we have a saying here: don't pay attention to what they SAY pay attention to what they DO.
i hope he does all those things but in my experience, my xABF would say just about anything when he sensed i was leaving. he rarely did any of them.
quack, quack, quack.
one day at a time. just get through today, mischa. continue to make your moves, such as cancelling the payment of the storage unit and notifying him of the deadline.
after that, it's really his affair. best for you to step back.
i wouldn't be surprised if he does NONE of those things. you might have to take some steps to get his stuff out of your house. i don't really like the idea of him coming there, even with a police officer.
is there an alternative place you can leave his things for him?
