How to disengage - confused

[Notwhat1signedupfor]

Hi all. Quite new to MN so please go easy with me! I need to disengage from my adult sd for my sanity and my marriage. I’ve put in a lot of years with her but she is nearly 30 now and things are not great between us. Currently we are NC but it’s only been a few weeks. We have to go to a family party soon which is going to be a challenge. How do you truly disengage from someone who is still active in the wider family? Do I just distance from all of them? (inlaws - we’ve never been close tbh). I don’t know how to go about this with dignity and class!

Sorry! I don’t know how this posted twice. Please see thread from earlier

I'd advise you not to distance yourself from all of them, you don't need to do that. Just be civil when you do come in contact with her, and ignore her at all other times.

My mum and my half sister never had a great relationship, and they were pretty full on awful to each other for many years. That's what worked for them, they're civil when we're all in the same place and at other times they just don't contact each other.
