DP and I went to school nativity today and while we were waiting for it to start he opened his whatsapp and the third person down was a girls name (first name and surname snd whatapp photo) that I had never heard of. We've been together for 6 years and he has never mentioned anyone by this first name before. As soon as he opened it he quickly closed it again without going into any of the messages and it's been niggling at me ever since.
We both WFH ,everyone from his work is male, he plays sports twice a week with all males, he has a couple of female friends and there is never any jealously on either side so he would have no reason to hide something and he is an oversharer so if someone was texting him he would generally say but there is just something about this that is niggling me.
I don't really know what advice I am asking for by posting this thread but I just feel that something is off about it and wanted to get it off my chest. I have tried googling the name but nothing comes up and I am not 100% sure that I got the surname correct as he closed it so quickly.
