So I've posted before about this but really need advice what to say. Ex is a herrione addict. I called the police to have him removed over a year ago. Social services got involved helped me. Said ex was to have supervised visits in open spaces in public. Which I kept to. I'm in the sheliding group and would require public transport to see him in do not belive for 1 second he's clean even though he pretending . He is on medication which also shows up as opiate so tricks the test which Dr is fully a wear of. Any way he's just called me and told me I have to give him money next week so he can buy a pad to do video calls as he doesn't have one. At the moment contact has been phone calls . I said no I can't afford to help u. So he started shouting at me and saying goes he is going to ride his bike here. What can I do. I will call the police if he turns up. But am I right in not letting him see our son. Or am I being a horrible person. ? Thank u
