Husband has a female colleague he's known for a few years, when I was using his phone the other day a message from her popped up and I couldn’t resist having a look, it was just about a shop she’d been to and she was saying he should go, I was nosy and had a quick look through older message, there were lots, back and forth 5 or 6 messages every other day or so including weekends and some evenings and also quite a few when we were on holiday last week! There are also lots of calls in his call history on his work phone made during the day.
He does have to work with her but not in a way that requires this much interaction and I can’t really decide how I feel about it. They are not flirty or inappropriate, there is nothing in them to suggest that anything is going on between them, I know they don't see each other outside of work and they could easily be messages from a man but I’m still a bit uneasy about them having this much contact and how they seem very familiar with the way they talk to each other.
I don’t think there is anything going on, I asked him about her, he didn't seem at all flustered, didn’t seem bothered that i’d seen her messages and said they just got on well and were friends. If I asked him to reduce contact I think he would but don’t know if that would be unfair if this is just me being a bit possessive? I wouldn’t ask him to stop texting a male colleague in this way, would you feel the same way or am I being silly?
