Separated 15 months ago. 3 dc. Two over 16 and 1 ds age 9.
Ex wants to see ds but hasn't seen all 3 dc in 10 months.
He contributes nothing and has made no effort to see them .
Last visit was in January when he slagged me off, frightened youngest with his rantings and told him he would have to choose who to live with.
He smokes cannabis every day, lives with his mother in , sleeps in the lounge, has no job and mental health issues.
Older teens have blocked him on phones as he would not stop sending messages that were abusive about me. He threatened suicide in the summer to my eldest and we had to call the police.
He has now out of the blue text me 3 days in a row after no contact for months asking for his ds for 3 days over Christmas. He wants him Christmas eve to boxing day.
Just him.
Ds would be terrified.
He would be devastated to be without his sisters as well.
I've been ignoring the messages but today's are him saying he is going to take me to court and report me to social services for brain washing his child against him.
I'm just ignoring them but feel it escalating.
What should I do ?
