A new couple had shifted to the flat next to us sometime back. They are both very friendly with us, and since our kids are of same age, around 6 years, we have started going out as families during weekends. Last month, we had gone out on vacation, where we all had had a few glasses of wine together. This night, this neighbour got very flirty, right in front of my husband and his own wife. It was taken in jest by all of us. But since we have returned, he has started acting a little too familiar around me. I am not comfortable with this. Both our spouses seem oblivious to this change. Am I imagining things, and making a molehill out of nothing?
