Gut feeling not comfortable about husband and his female colleague. I trust him and here are no signs of anything between them yet. They have worked in the same group the last 3 years. Sometimes give each other lifts to/from work events, though he does that with everyone. Every couple of months or so he goes out with bunch of workmates she's often there too, they message at times but he usually shares most messages and most of the times its do with our daughter and hers who are friends and the same age. Was going to take the kids over one afternoon to see him on his lunch break then he told me he's going to the park with her for lunch. He has been out for lunch with other male colleagues before and at times another female colleague with his other workmate there too.
The last free times I've been out with her she seems uneasy or avoidant, with him there and without, she doesn't chat as much, moves on to someone or something else regularly and only looks straight at me briefly and something feels off. Maybe she has a crush on him or he's been confiding personal things to her, I don't know. Any thoughts?
