No matter how conservative your mother might be...or if she still asks you about girlfriends..doesn't matter..she KNOWS you the best...you can't really hide yourself in front of her...and even if she'll act surprised when you come out..trust me, she was probably aware a long time ago...Mothers know their children and their feelings, so who knows, maybe this was a sign that she already want you to come out or something....
Anyway explain her that next time she's going to browse your phone, she should ask you first and you should deserve privacy...
