28, he will tell you nothing, and it will just alert him to your suspicion and make him more careful.
My h was cheating (at least online) for near 6 years before I found out, after not cheating for may 14 years.
I would fine all sorts of odd bits of stuff, such as facebook accounts mysteriously closed down afetr I added him and new myspace accounts opened and denied, plus new email accounts which 'i'm sure i mentioned', plus the odd photo of a woman, different each time, 'downloaded by music from torrent sites'.
What I learned is that I should have pursue my suspicions more rigorously to start with, and snooped very quietly but alot more professionally.
THe main thing I learned is that:
- there is no 'sort' who cheats
-they always deny until you can prove
- no normal rational woman has that uneasy instinct without good reason.
That last thing- the self judgement about turning into a snoop or as bad as him, about being a nice person, about possibly ruining a good relationship with a hard working innocent man.
We have all been there. My h admitted to me finally that he relied on that attitude from me.
If you think something is wrong, it probably is. Being away from home and very stressed and workaholicish (like my h) are VERY bad signs, and fertile ground.
You have also added in alot of the classic- careful with phone, deleting stuff, a bit family disengaged,having a new account not mentioned etc etc.
I would put money on it, from the outside, that this is not good news.
