Trust is a basic building block in every relationship. If you dont have that most fundamental piece in your relationship, then you should consider ending it. You aren't married yet (luckily), so it isn't that complicated.

However, once you start tracking your gf, you might gain temporary trust and relief from the hacking source, and perhaps even more confidence in your relationship if she isn't cheating. But if you do so, you will always be dependent on a 3rd party source rather than her words, and it will break you eventually.
