DH and I both work at the same school. He is in a more senior position than I and has more responsibility. I work part time as we have young DC.
I have grown a bit jealous of his relationship with a younger colleague that works beneath him. For instance, today at work I saw them laughing together about something at one point, then later on during the day he went up to her and said something and she jokily pushed him back. When he was leaving work at the end of the day I also saw him smile and wink at her as he left.
I don't know if I'm feeling irrationally jealous or something is actually going on to be worried about. Do you think this is normal behaviour? She is at least 10 years younger than him/us. :(
