How long was it between texting him you know about his cheating to the time he got home?
The likelihood is the OW and WH had ample time to sync their stories and you were delivered the watered down version. The time away from you, since they’re together at work, has given them the chance to scrub evidence, work out a plausible story and found new ways to continue. Even if he makes a big show of NC/final goodbye it’s likely he warned her that would happen, he doesn’t mean it.
Since he has given you access to his phone/internet download all the cheating apps, signal, telegram, whatsapp, fb messenger, reddit etc etc and request a password reset using his email address given. It’s likely he might have set up accounts and if you get a link to reset a password you know he has been using them and deleted the app during his big cleanup when you gave him the heads up.
Are the messages you read still on his phone? Him deleting those prior to handing over the phone also shows he is in crisis clean up mode.
It’s disgusting he baited you into the message about your sexlife. Look at his actions don’t listen to his words because you know he can lie to your face without guilt.
I’d hide a VAR in his car, some look like keychains these days, drop it under the drivers seat, also place one in the home office if he has one. A girlfriend of mine recently caught her partner by setting up her iPad to video record and placing it in the room angled towards him then went for a shower, it recorded him instantly on his phone and touching himself when she was out of the room.
It’s still early days but, when you can, look up the typical things cheaters say and do after discovery, it has the nickname ‘cheater’s handbook’, there is no actual book, but you’d be surprised at how unoriginal the excuses and lies are, this "just" a kiss is utter bullshit, thereis never anything "just" There is always more.
To fortify yourself read up on either grey rock or 180 method and have those as reaction tools, drink water and get sleep, it’s so important early days. I relied heavily on meal shakes since I couldn’t feed myself, consider those too if you’re not eating much.
Get STD tested and be honest with the doctor about the why, they might offer you something for anxiety and sleep. Also have the hard talk about exposure via breastfeeding, see what the doctor says.
This is a big one, never update him on any plans or activities you set if you are considering D. You keep all cards close, even if you go down that path and it’s good for you, don’t utter a peep.
