Thanks all for the support. Honestly, I expected to be told that talking to them was wrong, and I should not have done so (perhaps people are thinking it and not posting... I d/k).
Update: Wife had (or is at-this-moment having) two separate medical proceedures today. I just left a voice message for her, telling her I was calling to see how she is doing, telling her I was thinking about her.
This is the first time I have called for the sole purpose to seeing how she is doing since June...
