DH has always run two phones as he has one for work then his own personal phone. Nothing suspicious in that and he occasionally leaves his own phone at home (unplanned) as he barely uses it except for social media and the likes that he can’t do on his work phone. Yesterday he managed to forget his work phone (he’s away overnight as he always is on a Monday - I know where he is) so I answered a few calls for him, just from work colleagues to, to tell them to get him on his own phone. He was a little twitchy about it saying he’d email everyone and just to turn it off, but I didn’t really think anything of it. Then a Kik notification appeared. Nothing outrageous or anything, just a “Good morning you”. Seemed a bit odd to me so opened the app and turns out the only people he had on there are two women. One who he hasn’t spoken to since May and seemed to be a one off chat about their lives. Totally weird and general chit chat. The other one though he talks too every day. And multiple times a day. About his work, her work, even the fucking weather (she lives hundreds of miles away). They also clearly talk on th phone when he’s driving (he drives a lot for work). There’s nothing overtly sexual in it, a bit flirty which is his character a bit, but I’m gutted. It’s every single day. There’s no explaining that is there? Everything I can see online suggests kik is well used for affairs.
