checking his phone?

[jdjejsn]

DH has been acting very suspiciously with his phone lately, taking it to the toilet with him, always keeping it on him which he never usually does and i noticed he’s changed his passcode too, AIBU to have a quick look through it? I would straight up ask him but don’t want to seem paranoid

To me, it definitely sounds suspicious. I know people don't agree but I personally would have to look.

I'd look.
Problem with asking is if something is going on then you've basically told him to be less obvious so he'll delete anything suspicious, tell OW to back off a bit and then you don't have a clue.

If someone asks for your phone when you’re not expecting it, I wouldn’t be happy to hand it over there and then. Not because I’ve done something wrong or I’m having an affair, but usually because I’ve been googling or have unusual websites open, nothing sinister at all but not something I’d nessesarily want others to see.. Eg could be something like a mumsnet thread open, and the person will think why have they looked up a thread about asking for advice about leaving their OH, or having depression, when in reality you are fine but were just having a look at the latest threads.

PS, men take their phone to the loo, it’s something to read.

My phone is my own (as is my iPad, my handbag, my coat pockets, my diary, etc). If my husband were to ask for my passcode, my face would tell a picture alright.

OP, I agree his behaviour is odd, if ot is a change from normal. I'd just keep my eye out for other stuff though, and not manipulate use of his phone etc.

As an aside, people who cheat (and I'm not saying OP's husband is doing so). Why the actual fuck do they keep stuff on their phone? It isn't hard to delete messages/photos/whatever. If you really want to keep stuff, it's easy to email screenshots/photos to a secret account, or elsewhere in the cloud. (I appreciate this sounds like I've given it thought, which I have from an academic POV).
