Just realised wife of 12 years is having a MLC

[Detrmnd]

So we meet for parents evening at 7pm I am going out straight after at 8pm. How vague should I keep things, and is it ok if I go all dressed up or will this antagonise?

I guess I am unsure as to what is the best course of action whenever I see her. Is it fine for me to be dressed up and have plans. But I should say nothing unless asked and remain remote or "dim" as someone put it? And if asked give the bare minimum info such as "Oh I'm just going out later".

Sorry to be asking all the time guys but I made so many mistakes and I am as my handle says "Determined" to make a better fist of DBing this time!
