One of the hardest things for me to learn was to give my wife time to process things her own way. I overthink while she is doing this, My mind fills in the blanks where I have no right to fill in yet until she is ready. I still do this to this day.

Sometime just leave that conversation alone for the time being and turn something more positive like a simple I love you, and as long as we are together, we will get thru it.

Support and remind your SO but let them process their own way.
