Does this sound like suspicious activity from my husband or am I being insecure?

My husband (34) and I (30) have been together for 8 years. I have only looked through his phone one time, which I usually avoid doing as I don’t want to invade his privacy. The time I did it was within the first 2 years after I’d given birth to our son and my postpartum issues had me feeling like I was going crazy. So I looked through his phone… I did find some upsetting things, to which he said “if you go looking for problems, you’re going to find something”, but I got over it and 6 years later I’m starting to feel the urge to look again as I’ve noticed some odd things happening. I’d really like some advice because I WANT to trust him and want to say I’m just being insecure and there’s no need to look… so let me explain and please someone tell me if my feelings are reasonable or if I’m just “looking for a problem”.

About a week ago we were laying in bed together and he had a Snapchat notification pop up about his “memories” which he clicked on and it popped up a funny pic of me. We had a good laugh and I said “send that to me because I want to turn it into a sticker”, and he acted like he didn’t know how, so I reached up to click the “send to” button and he kinda jerked his phone away. After you click that button, it immediately shows all of your “recents” and “best friends”, so my first thought was that he didn’t want me to see who he’d been talking to. I didn’t say anything because I thought maybe I was over thinking it. Then again last night, similar situation. He got a memories Snapchat notification that he clicked on and it was a cute one of me holding my son as a baby, which I’ve never even seen, so I told him to send it to me. But he swiped out of Snapchat and I said “no I’m serious send me that, I want to have that picture”. So he went back and went to send it to me, but he did it super fast, like he was intentionally trying to send it as fast as he could, because my guess is that he, again, did not want me to see who he’d been snap chatting. I did catch a glimpse of the 2nd name under recents, and it appeared to say “Courtney” but he was too fast for me to see the entire name. He doesn’t have any family member with that name, and no friends. I also noticed when he first swiped out, he accidentally went to the “memories” part that shows all your last Snapchat’s and stuff that you’ve saved, and there were some selfies of him that were definitely not sent to me because he doesn’t ever Snapchat me. He will respond with a “chat” if I send him something and that’s it. Still didn’t say anything and now that I’m getting into my head about it, I’m trying to add things up… like the fact that he’s hypers3xu@l and wants it multiple times a day typically, but hasn’t even asked in probably 2-3 weeks, which I was sick all this past week with a respiratory infection, but that’s never stopped him from asking before. I also think about the nature of his 2 jobs… one working at a cellular service place (where he’s mentioned girls coming in there and having s3xy photos on their phones and don’t even try to hide them), and his other doing grocery deliveries and going to random people’s houses.

Please tell me I’m overthinking and don’t need to look 😭 I don’t want to bring it up to him first because then he’s just gonna delete stuff and hide it better so idk what to do.
