If you found texts on DH's phone from a female colleague, who you knew nothing about? Lots of meeting up, apparently mostly for work, but not always, sometimes it was "just to catch up". For the last 2-3 YEARS!! Obvious flirting, but nothing to suggest anything physical has happened. Although one sexual remark, which was "a joke". Feels like I've discovered an affair, but he's adamant it's not and that nothing has happened. Don't know what to believe.
