I think my g-friend might have stolen my identity and used it on the internet how can i find out
It will be very hard to know that someone used your internet account on the internet. You might however notice some changes with the settings or history tabs. It will be easier to know if you catch them in the act.
If you see purchases on your cc statement like, Victorias secret, coach, and Kay Jewelers...you've got your answer. if she did that, she's not a very good gf.
