You don’t have to fight or argue with him, you just have to say no to him and let your solicitor negotiate.
You don’t have to get him to agree with you, or convince him of the rightness of your position.
You don’t need to defend yourself when he says you are crazy / abusive / whatever. You just keep All the emails / texts / screen shots in a separate folder in case you ever need them.
You don’t speak on the phone unless it’s an emergency about your son.
You don’t meet him without another adult present, if you can possibly avoid it.
You stop playing fake happy families and having him in your house at all, let alone for meals. If your son asks, you say that won’t work for you and that you and his dad need a bit of space. That you understand that might be disappointing for him but that’s an adult decision that you have made.
You don’t ever go in his car.
You can’t “ remain amicable “ with an abuser. He will just use this to Perpetuate the abuse.
You need to keep him at arms length, physically and emotionally.
I know this is really hard, unimaginably hard for anyone like you who has been groomed by an abuser . I bet you even feel sick just reading my words.
The thought of disobeying him is terrifying, isn’t it.
