Here's the scenario. My wife works part-time and due to her work situation she works quite closely with a male co-worker. They have become pretty good friends over time and our families have a lot in common. He is married and he and his wife have children that are similar in age to our children. So they swap funny kid stores and the like. All of this I have zero problem with. I've met him and his wife during a lunch date and they're a great couple. Recently they left work and went to lunch together just the two of them. I only found this out because she was telling me about her day and I asked her where she went to lunch. I asked her who she wen't with and she told me that she went with her male co-worker/friend. Had I not asked, I would not have known.
I feel somewhat uncomfortable with my wife feeling comfortable going to lunch with her male co-worker/friend and being alone socially together. I'm going to talk to my wife about how I feel about this, but my question is, for those of you who are married, what boundaries have you set in your marriage regarding the scenario I've described? Is this acceptable behavior in your marriage, unacceptable?. I trust my wife completely, I just feel like this is perhaps how a lot of inappropriate relationships start. Completely innocent at first and then... who knows down the road.
