Newlywed and in crisis

[funbun]

Hi DB Forum,

W’s uncle will have a birthday dinner tonight with W’s side of the family. He is a nice man. He’s knows of my sitch and he’s inviting me over later. I said I will come. I notified W of this so that she won’t be caught by surprise by my sudden appearance there.

I plan to be cordial with W later, but also will try to minimize our interactions. I can tell I am still not fully detach and still harbour some resentment. I do not want that resentment to manifests itself in my behaviour towards W. No interaction is better than bad interaction right?

Any other advice about code of conduct around W? or maybe a few words of wisdom to set my mind in the right frame (i.e. minimizing sadness and resentment)?
