He's getting desperate Ican. Stamps his feet because you've blocked him, not liking that you are starting to assert yourself. This is the time you need to remain firm. I'm glad you had your friend with you for support.
Does this latest behaviour contravene the Orders made? Blackmail is a crime. One of the lowest.
Dont give in Ican, it will get neither of you anywhere, and probably wont be the end of it until he sees you mean it, or feels the consequences. He will take you for everything otherwise, and not only money. What a little prat.
Congratulations on 11 days.
