My ex and I have been separated for over two years now. We have no family court orders but have been to mediation twice and done parenting plans (I know not a legal document until stamped as such). My ex moved three hours away about 3 months ago, so the parenting plan went out the window. He only had requested 4 hours access over a week period spread out over three days. I offered for him to have our son for a week during last school holidays and he lasted just under a week before demanding I drive 3 hours to pick him up as he had enough of his behaviour. So I did. Since that time (2 months ago), he had no contact for one month and then one phone call per week up until now. He hasn't seen him in two months. He has demanded I drive our 5-year-old son to him for Father's Day as he has no petrol. I've told him it's a six-hour round trip and too long for our son and if he could meet half way to see him for a couple hours. He agreed, then later that night, sent me a text saying not to bother with it, he's over it all, etc. Sorry having breakdown. I left it until the next day and said okay, won't meet and can call him if he wishes to. He has now started in with talking about lawyers, etc. and going for full custody of children, etc., which I've already contacted legal aid and lined up more mediation because I'm sick of the abuse and the inconsistency for our son. My main question is, he is still demanding I drive him to him on Sunday. I have told him repeatedly no, I won't. He has spoken to our son and told him the "mum is bringing you to see me on Sunday for Father's Day" and has now sent me an address where he wants me to go. How do I reply to this? I know there is nothing legal in place and I hate that he has told our son that I am doing it when I'm not and now I have to try and explain it to him. But what can I do in the meantime? Do I give in and take him ? Or stand my ground? Sorry, for long essay but I'm at my wits end and so overwhelmed with the verbal harassment via text I've been receiving and he just doesn't want to take no for an answer.
