DB, I get exactly what you are saying. My SIL got married today....and I’m just now seeing FB pics of the wedding and my W and S all over the place. And there’s a distinct place left vacant where I should/could be. I can’t concern myself with it.
I’m pissed to no avail to miss half my S childhood for W “happiness”
Just continue DB and practice patience.
