Really need your advice on this, have discovered an email dh replied to a female work colleague, he addressed her as "hi gorgeous" and ended in "I am really looking forward to seeing you!!!! (at a work social event), I have also read another email in the past in which another female work colleague informed dh that a friend of his had blanked him because his girlfriend who dh also worked with had described dh as sleazy towards her. I have also found images on dh's mobile of a few photos taken at work with this attractive female colleague in the centre of the picture who I think maybe the colleague he had address as "gorgeous", as she was at the front of two of the photos.
We have been together for a very long time and have a very close relationship and active sex life. I confronted dh over this and he said he does sometime flirt to boost his ego as he has never felt good enough for me and always thinks I am going to find someone better. He is always the tactile loving one in our relationship and I admit that I have been cold towards him in the past, but I do genuinely love hime and this has all really shocked me.
