Don't know what to think

[T-boned]

To continue my grocery store encounter with my H, after we said our good byes near the eggs, we both went on to finish our shopping. When I got to the check out area, there he was in line so I waved - he waved back. But I recognized the woman with her young child behind him in line. This woman is also going through a rather rough divorce, so I went over and spoke with her for a minute. H could probably hear every word, so it was rather awkward when she says to me, "Boy, we've both had a rather rough year, huh." I kind of rolled my eyes and said, "Oh ya." Funny thing, I think she had been talking to my H while in line but didn't connect the two of us when I came up to talk with her. She has seen us together on several occasions in the past. Anyway, I got in the line next to them, got my stuff paid for and out I went. Didn't even turn to wave goodbye to H. Was that rude?
