"I have 2 lines, the second is my work line, but the company won't let me use my first line" "I want to get text messages, but they should still stay on the phone". "I don't want to carry the phone with me" HA HA

BULL****. You want to spy on the chick you have a shared line with.

The solution to your problem is to dump your girlfriend. You obviously don't trust, nor respect her. With you lacking trust for her, you'll eventually persue hopping the fence because the grass looks greener and you'll use your mistrust (read negative judgement) as justification.

It's too late for you.. let her go. Break it off.
