I went through my partners 'M23' phone 'F21', dating for 3 years

As the title says I went throguh my partners phone a while back,

He met this girl though a friend and it's not like anything happened they've only seen eachother a handful of times. And she no longer lives in the same place.

Feeling insecure or wanting to know how she was acting towards him I went into their instagram messages, nothing special was there not too many texts, just about if he was coming to x place with others bla bla.

She came off as a little bit flirty but he was normal.

After that I actually met her, and she was quite impolite to me and because of some other reasons I thought she didn't like me becuase I was his girlfriend and wanted to move on my bf. I mentioned it to my bf but he seemed to disagree even though I'd say it was obvious she liked him (e.g. bought him a drink while out (first time meeting him), not being nice to me or even introducing herself to me, posting him on her story)

Anyway later I know he told me she sent him a few reels or some stuff.

So after a month or two, I had this urge to check the messages again, and there was barely any texts (just one short convo) but the rest were deleted, there was no reels, no old messages and her profile icon popped up at the top (implying that theres no more messages).

This was a while ago and I never mentioned it but i think it's weird. I know I shouldn't have gone through his phone, but this is bothering me and I am not sure what to do about it.

I tried subtly asking him about it, but nothing really came out of it.

Is talking to him a good idea? Does this seem suspicious to you?
