I left my BD a year and half ago due to abuse and since then he refuses to see my son. My son is now 2 and half and we have had no contact apart from me initially trying to get keep them seeing each other safely e.g. supervised contact with my parents in my parents home as BD is abusive towards me my son experienced him abusing me. BD refused and then months later threatened me with mediation and I attended the meeting and he didn't want to continue on as it was another one of his abusive control tactic. Then months after that he asked to see my son and I suggested a visitation centre. BD asked for details and I sent him the forms to fill out and nothing, again due to the money. He fought me a lot as he didn't want to pay child maintenance and threatened me a lot. This all happened within the first 6 months of us being separated and them silence for the whole year.
Now randomly, he has decided to message me today after a whole year or nothing saying he wants to talk to my 2 and half year old son. I don't know what to do. I'm feeling very territorial. Any advice?
