Zoo with all due respect you were counselled to ask colleagues / PA to filter your work voicemails a long time back.
You also have the option to not listen to them, skip and delete - as you have done to date by blocking all other channels.
Why are you still actively engaging?
You must understand by now that the content of his communication is irrelevant and it just a method of harassment?
I am also very concerned that you actually put out “option b” ie to RESPOND to him - in all seriousness for consideration.
Also you can’t really “need” the sports kit if you haven’t even noticed it’s absence in 7 months - let it go.
I am not surprised you are stressed. I have given the analogy before that this process is like a game of snakes and ladders - you are making progress and then when YOU engage with contact (because you DO have a choice here) - you slide down a snake, end up hurt and regressed.
Do you WANT this drama? Do you need it?
Each day you engage it is a day further from your happy ever after - you are allowing your internal world to be preoccupied with this toxic past - which is holding you back from your brilliant future. You have made great strides in the practical, external changes - but I am concerned that the emotional stuff is lagging behind. Don’t count on the move erasing all of this - as wherever you go - there you are.
Are you still seeing your counsellor ?
