Okay, so this is really bad, but… He actually clocked it pretty much immediately when I got home because he felt something was “off” and he suspected I met someone. I didn’t have the courage to tell him the truth then; I thought I would just tell him half the truth (“I really connected with a friend while I was away and we spent a lot of time talking, and I’m just really missing that with you in our relationship”) and then I figured he would talk to me more, and that I would end it with AP and bury the real truth… but neither of those things happened. Like I mentioned, he withdrew, and then I took that as a sign that he didn’t want to talk to me, and then I went back to talking to AP.
I knew I couldn’t hide that I was texting someone, and DH has my phone passcode. But I figured it was okay for me to have a “friend,” so when AP would text me, I would leave our platonic messages on my phone and delete the flirty/sexual ones. I also knew that there was a deleted messages folder on my phone and that I should have cleared it regularly just to be safe, but some of the things AP was saying to me weren’t adding up, and I kept going back in to read them to make sure I wasn’t going crazy, and I didn’t end up deleting them permanently.
DH’s spidey senses were still tingling the whole time, because I was still acting off, and there were a couple times I woke up looking kind of panicked and trying to find my phone, since I was having nightmares about him finding out. And though he looked at the messages I’d left un-deleted, he thought the number didn’t add up to the number of times he’d seen me texting.
So late one night he started googling how to search your partner’s phone if you suspect they’re cheating, and a Reddit post told him about the deleted messages folder. So at 3am he screen shotted several sexual messages and ones talking about meeting up that weekend, and sent them to himself in case I tried to deny it.
Then he woke me up at 5 am and while I was still half out of it, he told me he knew. I was kind of glad he did that, because I was too sleepy to come up with any more lies (not that I’m sure I would have) and just admitted everything.
I didn’t originally ask how he found out because I didn’t want to be better able to avoid detection in the future, but later in the day I used his phone and saw the screenshot he’d sent himself. Of course I deleted them, because I didn’t want him to have those in case he decided to at-fault divorce me and take away the DC, and then I went to check his search history on all his devices to make sure he wasn’t looking for legal advice or other signs that he was planning on leaving me. That’s when I saw what he’d looked up overnight, and about 20 different searches with AP’s name.
