Look - if you run away with your wife and your child you could very well be arrested.
A few things:
If your wife hasn't been in contact, how do you know she wants to run away with you? That's just something that isn't clear. If you run away with her, the chances are that she will say that you abducted her, or otherwise forced her to go with you. That could very easily lead to a jail term for you.
If you run with just the child then social services are going to see that as the strongest possible evidence that they are trying to obstruct them doing their jobs. Look in the last thread I said you needed to start looking at this from a perspective of "They want what is best for my child. I also want what's best for my child [Presumably]. What can I do to show them that I am a capable, trustworthy parent?".
I never said it was going to be instantaneous. It will take time and effort, just like anything in parenting. And I don't doubt how terrifying it must be to have the threat of your child being taken from you.
But look - You cannot simply keep denying that there are any problems, that the world is against you, and that this is all a big lie. Because if you do that, you are telling them and everyone else "there are no problems, therefore nothing needs to change".
The fact that social services are even considering taking your child from both your care should be a massive wake up call for you. There is something quite clearly very wrong with your relationship with your partner right now.
You need to work out what you can do to fix it in order to provide a home that objective bystanders would agree is safe.
What you cannot and should not do is give social services the message that the welfare of your child is not important to you, provided you get to stay with them. I'm sorry, but it doesn't work like that.
Look, in your last message you said that you were worried that your partner would harm themselves and possible the child as well. If anything this news should be a huge relief to you. Social services have agreed with you that she isn't suitable to be looking after your child right now. I don't understand how someone agreeing with something you yourself said is suddenly them being the bad guy.
