Friendship strained by unexpected romantic request in the US

A 76-year-old man feels uncomfortable after his longtime friend's wife suggested kissing on the lips instead of the cheek. This request has caused him to distance himself from the friendship. He questions whether he is being too sensitive about the situation. The advice given suggests that he should communicate his feelings to the wife to clarify boundaries and potentially restore the friendship. Having an open conversation may help him express his discomfort and understand her intentions better. This could also allow for an apology if necessary, helping to ease the tension.
