DH has form of lying and has previously been caught out messaging other women etc.. and a previous emotional affair. We have had counselling and talked at length about boundaries and things that trigger my suspicions (that have on occasion been incorrect) but of course I am not at peace as yet on this road to recovery...
He's been away on a training course for three days this week in his relatively new job. I knew he was in a group of men and women and he said they are at the pub each night etc.. all fine.
I mentioned something regarding COVID19 this evening and he said ah yes I know about that; I was sent some pics by someone. I thought 'someone' 
and asked who... he said a woman on his course. He seemed quite coy and I thought rather than jumping to any crazy conclusions I simply said ah can I read them (meaning the messages regarding the topic but also I found it strange he's swapped numbers with a woman from somewhere else in the UK who he will never see again and bearing in mind the fragile road we are on).. but guess what; the messages have been deleted! No number, no messages. The photos she sent (albeit covid related and innocent ) are still in his photo stream but it is strange that he has deleted the thread when he never deletes anyone else's messages!
Thoughts wise mumsnetters?
He says he didn't need them. Usual bullshit! I feel it's the same as all the previous times; if nothing to hide then why delete- then I can decide for myself? I can't cope with this level of uncertainly and mistrust. I just needed to write it down I think.
