Its not in a contact centre (it was supposed to be, but his solicitor failed to sort their end out, and it never happened). We meet in a neutral venue, but have to arrange it between us so we know when to go.
We previously arranged block times, so set out the next however many sessions, but if he was busy, he would cancel and say he would just se her the next time, but at monthly, thats a while in between. We started just arranging it every month, him texting saying i''m free these days, are you, me saying I can do this day what time, him saying the time and then thats that.
It broke down though, when he wouldnt text me to arrange anything and then blame me saying I should have text him.
I don''t know if a go between person would work. His mum won''t talk to me, and my mum won''t talk to him. My mum used to supervise the contact before, but hated it.
We don''t contact each other a lot, its supposed once a month, but its usually less.
