I had a gut feeling...

Well... I had that gut feeling... You know, the one that you just can’t ignore because you keep seeing the signs...? My boyfriend started hiding his phone, sleeping with it under his pillow and such... as if I wouldn’t know after the amount of times I’ve been cheated on (not by him, just in general). So I come home one morning with the attention of going through that phone one way or another. I needed to put my mind at rest. I had asked him about why he was sleeping with it under his pillow, but he, of course, said that it was just so his alarm didn’t wake me up and that he had nothing to hide. So I went in, got that phone and when he woke up as I was beginning I acted as if I was putting his phone on charge, I mean after all it was about to die. Then he asked me to hand him his phone. Instead of handing him his phone though, I opened it up, and just got on his Facebook. He asked me what I was doing so I just said oh scrolling through Facebook. He got up and stayed leaning over my shoulder even though he was tired, and then he was getting agitated about me being on his phone. He just said he was agitated because he was going to look at Facebook, not because he had anything to hide. So I finally was like wow it’s weird that you’ve been -insert list of suspicious activity- since you have nothing to hide... 🤔. So then I said ok well I’m going through your Snapchat and everything then. He said ok, not knowing that I had gotten ahold of his phone for a few minutes days earlier and had time to change all his snappers to no deleting for 24 hours. Facebook was clean (I expected nothing less) and Snapchat was surprisingly clean except for a few people he doesn’t know where he was just commenting on their story... I was like ok, maybe I’m wrong... maybe I’m just being crazy, or bringing my past into this. But then I decided to look at his friends on Snapchat... and low and behold, there it was, his best friend for 2 weeks in a row was boom, right there. No record of their messages, but instantly I knew. A girl I had met at Kroger’s with his children that I have been raising with him (because we always go to the grocery store together), who happens to also be a girl that he works with. Of course a younger girl as well, but not particularly pretty (not saying I am, but I’m quite a bit cleaner that this girl). He couldn’t deny it, he fessed up without there being any evidence other than that. And now here we are. I decided to forgive him, decided to try to move on from this... but I don’t know how. I’ve tried this before and it’s just ended up biting me in the ass in the end, because they just did it again. He confessed to me that he didn’t even know how it happened, but nothing more had happened other than the snapping and flirting at work. That he had only touched her when in passing at work, like to move around her, that nothing was ever physical more than that. Which is one of the reasons I decided to try to work this out. I feel like I’m going crazy though, I keep wondering how I’m going to do this. He works with her, he works with her only like 4 times a month, but at this point 1/2 a time a month is too much. So to the ladies out there who have been strong enough to do this, I have how? And did it work out for you on the end?

*UPDATE

I wanted to clarify something, he has not done this before, men I’ve dated in my past have. I just saw a comment and wanted to make sure that this was out there.
