hi nano, welcome to this friendly forum,

seems maybe you dont trust your loved one,, checking her phone,?

trust is important, isnt checking her phone a bit like rumaging through her handag while shes not looking.

perhaps something has stirred you to feel suspicious i dont know but

going by the translation you have been given, it looks quite innocent, obviously someone she hasnt seen for a while ie asking where she work now,,,, she tells of you ,invites her friend to come with you both by the looks of it, friend could be male or female ?,

dont worry relax, no relationship will work without trust, when the times right you should talk with her about it if it troubles you , dont sweat in silence, good luck to you with this
