Have you ruled out your boyfriend?
Not accusing him. But...
I’ve been in a lot of relationships. And I’ve found from experience that “someone” always turns out to be them.
If I went from experience of my past messes... here’s how I would expect it to happen based on what you’ve supplied for information.
If accessed online, see below... spouses have your passwords (even if you think they don’t).
It doesn’t have to be done online to create the effect of looking like it was.
If your device is set somewhere while you shower, changed laundry, slept, etc...
Take pictures with another phone, and photoshop (or similar free program) them into what you were later given as “evidence”.
If your phone was locked... guess what... spouses always know your codes. Even if you think you’re careful. They know. I didn’t even have anything to hide, but I got tired of the bs in my last relationship and changed my codes daily. The only relationship where I even bothered locking my phone. Usually I’ve always left them unlocked for convenience. And I have no secrets from anyone I date. I’ll tell them every reason not to date me before it starts, yes I try to scare them off. Easier that way.
Anyway... point made.
If you have your phone set to use your fingerprint... guess what’s always handy while you’re sleeping.
It’s simple if one cares to try.
As for why??? Perhaps he has something he wants to talk about with you, and saying someone else sent this to him and said something... well... that’s a convenient way to get you to talk without admitting to snooping.
I’ve seen people go through all kinds of crazy stuff. I’m pretty sure everyone I know is drama... I hear so much stuff from both sides. I really wonder why some people are still together. Actually I know why... some people need the very thing they complain about.
Anyway, I’d go to iCloud and your Apple ID, and use the website to log out all devices.
Then I’d change all my passwords to something crazy long that is random with no words.
And as an additional step, if you have a newer Mac that is receiving your iMessage as well (like mine is) then I’d lock that down too.
And I’d turn off Touch ID and face recognition on everything.
That’s usually my first step. Then if my spouse is still a problem (as in I see that they’re not making progress to be trusting) then I get rid of them too.
I’m an open book in relationships. And that comes with an expectation of trust. I’ll tell you anything you want to know (and probably more), but if you show me that you don’t trust me, then I assume it’s because I shouldn’t be trusting you (and that’s always been proven to be true).
Now... in your case, I could be completely wrong. But, in my experience, that’s the way it goes down.
