I’m sorry, I understand that you must miss your children very much. And you must be angry at wat you believe is an unfair situation.
But for your children’s sake you need to understand that they have a new family now. It is very unlikely that they will come and live with you ever again.
If you pin all your hopes on this then you will not be able to come to terms with your current situation and do what’s best for your children. You will be stuck hoping for a future that’s unlikely ever to happen.
Please do not contact them on Facebook . If they contact you , please get in touch with your social worker and ask for her/ his advice.
Remember that you are not any legal relative now, however you feel. I’m sorry to say this as I know it must be very painful. But that’s the legal situation.
You could get in serious trouble arranging to meet up with a child who is under 18. Even if they are older , you both need proper supports put in place. If you work in a refuge you will know this kind of things can cause terrible trauma .
Can I ask you about the women you work with in the refuge - I bet all their ex’s want to get in contact with them , don’t they? Because they think they have a right to see their ex. They want to apologise and explain and tell her to come home, where she really belongs. To put their side of the story and explain that it was all a big mistake.
Some of them are married so they are even a legal relative . Or they have kids that they are father to. They have rights, don’t they?
Does your agency help these men to get in touch ? If not, why not?
Now think about yourself .
Your children have said that they want to leave things in the past . You need to respect this and let them move on with their lives.
