To want to maintain no contact with ex forever?

[rainbowlanyardsupmybumbum]

My relationship was abusive. Courts have given access to child, I will support their relationship.

Is it reasonable or viable for me to remain NC with this person though? I'm having visceral reactions to contact already (via app) and don't want to be friendly. Amicable of course, which we are, third party exchange, child's happy so I'm happy.

A link to this person was what I was trying to avoid but judge suggested we spend time together and cleared him of abuse (I would have called police if it had happened apparently)

But it WAS abuse, and I never ever want to see him again or speak to him, ever.

Its really unusual for people to want to go no contact with people that treat them well, isn't it!
In your case I think the best you can manage is low contact. Put boundaries in place about how and when he contacts you to make sure you can document everything - so for example, emails and texts, not phone calls. That will give you some control over when you read his messages.
And if you are very lucky he will be stupid enough to give you the evidence you need that he is abusive.

Gosh I wish I could do this with my ex I wish to never see him again or speak to him. I like the sound of what some people do which is collect from school on a Friday drop back on the Monday so parents never ever see each other again but my ex wouldn’t do that so unfortunately can’t work for us and I’m forced to see him.
