history: Many years ago, my husband was acting a bit too 'chivalrous' to a friend of mine, which I felt was a bit too friendly. He said he was just being nice, but I felt like he found her attractive. I've been married almost 23 years_comma_ but many years ago_comma_ my husband was acting a bit too "chivalrous" to a female acquaintance of ours. He said he was only being nice_comma_ but I felt he was being a bit 'too nice'_comma_ which made me feel a bit upset.  That is VERY understandable. Emotional affair is still a betrayal. 
current: Well, we really didn't know her very well and she actually just came to one of our friends house while we were there, and she was intoxicated. He was trying to help her get up and situated, but he was very insistent about it, even when she didn't want help. It looked bad to others.
next: Well it's nice he is kind but yes that is a little strange. Women can usually take that as something and try to get with your man.
