Would you be upset if your partner hid social media accounts from you?

I thought my husband had no social media accounts. He has acted inappropriately before on Facebook and made the decision himself to delete his account.

He went through a couple of his attractive friends photos, every single one of them, more than once. I found out one night he got super drunk and I was picked up his phone from the couch to switch off his network (we switch off our WiFi overnight) and when I switched his screen on, it was still on the page of his ex coworker. I then went through his history and saw that very evening he went through about 40 of her pictures, and he had done the same thing two days prior, and the week before that he went through her profile and another ex coworker, etc.

So tonight I saw on his phone, when he asked me to put it on charge, that he had a Twitter notification, so I checked and he also has Instagram too. I have neither.

I don't care if he looks up porn or wannabe porn stars or whatever. I'm just concerned that he didn't tell me that he has these two social media accounts.

Should I just leave it be? I mean I'm not his keeper that he's not allowed to be on social media.

*Thanks all. I'll bring it up with him. To answer some questions - I didn't go digging in his phone. I just saw the Twitter notification then went through his apps and saw he has Instagram downloaded as well. I didn't launch a full investigation, if you will.

Also, he has stated he doesn't want to be on social media at all. I once mentioned something about Twitter and he said he wouldn't know how it works, and he's always claimed how much he hates Instagram and felt it's just an attention seeking platform.
