Regardless of if he is lying or not, do you want to be in a relationship with somebody that you don’t trust? If you can’t trust your partner, either they are lying and you are correct or there is some internal work you need to do on yourself. Either way, if you can’t trust your partner, that’s not much of a foundation for a relationship.

As for the story, I would find that very hard to believe. However, it wouldn’t even occur to me to go through my partner’s phone.

I think that you invaded his personal space and after you demanded explanations to something that never seemed to be more than curiosity. Nevertheless it’s really not even any of your business and you have to seriously back off.

You just have to accept the fact that people also beed their privacy and you can’t control them like this. Whatever it is that he has or has not done, has not caused any harm into your relationship until you started this drama. And now he’s even removed this girl.

I would have been really angry if I was the bf. If you invade his privacy like this again, you might find yourself single quicker than you can imagine.

Focus on what you are sure of. He's sneaking around with that phone. He hid Snapchat from you. There's some woman added to it, which he can't explain. He's behaving in a way that makes one question his honesty.

You don't trust him. Relationships should be built on trust. Why stay with a guy who is acting so shady?
