Found a weird site on my BF's phone - should I be worried?

[PoliteDreamer]

I saw my boyfriend's phone screen for a sec last night and he was on a website called Anonsms. I'd never heard of it, so I looked it up. It's for sending anonymous texts where the other person can reply. My mind immediately went to cheating. Why else would he need to hide his number to talk to someone? I don't want to accuse him of anything without proof, but this feels like a huge red flag. Has anyone dealt with this? I don't know how to bring it up.

You need to ask him directly why he needs to use this website. Watch his reaction and trust your gut. I can't think of any decent reason he would need to use it.

I think he's either cheating on you or he has cheated on his last girlfriend.

I planned to wait for him to come back from a business trip to question him in person, but I was afraid that he would not admit it and then continue to deceive me, or should I also send him anonymous text messages to test him?

If he was cheating, why would he send the texts anonymously? Surely he’d want his partner to know it was him.

Good idea. Send something sexual and if he responds positively then you know he’s cheating or willing to.

What does he do for work? I’d wonder if there’s something nefarious going on, like blackmail or threats he’s sending someone, or alternatively he’s messaging sex workers, rather than having an affair with a known regular person (if you see what I mean), why would he need to be anonymous sending texts to an affair partner? That wouldn’t work; sure it would mean his name wouldn’t come up on her phone and vice versa, but any partner opening the phone would see the message contents and know an affair was happening. This app is used so the sender can mask their real number. You don’t need that for an affair.

Maybe this is how they talk privately? If they talk directly on regular communication software, it's easy to see it. If you send messages directly on this anonymous website, you will not leave a record easily.

If he goes to blackmail or blackmail others, it will be terrible. What is my safest approach now? I don't know if I should test him with anonymous text messages.

Sorry OP but my mind went somewhere dark. First thought was sex workers but most men don't seem to care about hiding their number from them, just their partners, so then it dived into underage chats with girls. It makes it harder for parents or police to find them.

I agree with pp. Ask general questions about the app and watch his body language carefully.

Get his phone and open the app? How feasible is that?

Could he have read about it somewhere and went to see
I feel like I want to go look but afraid in case the hubby sees it and I end up in his situation
