PSA for those of you who go through your partner's phones
I really don't understand why people think you lose your right to privacy in a relationship.
I don't have anything to hide from my boyfriend. I would never in a million years cheat on him. But I wouldn't feel comfortable with him going through my phone without asking me and doing it right in front of me, where I can see what he's looking at. It has to do with me having been in abusive situations where I wasn't allowed any privacy and could get in trouble for small, innocuous things. So think twice before you just start digging through something that doesn't belong to you.
A lot of reactions that people take as an indicator of guilt are also signs that someone has been abused before. You ask someone a question that comes across as an accusation and they get nervous, maybe even start crying? They could be accustomed to being accused of things they didn't do and being punished for it.
And yes, men can be victims of abuse, so don't even start.
Even if all of this wasn't the case, your partner still has a right to privacy. If they simply don't want you to go through their phone whenever you want, that's their prerogative. Being in a relationship doesn't automatically take away that right.
