Get to know her, get to know her friends and her family. They will be your best support ever. My ex was lying to me and scammed me! Her Aunt told me rather than have the shame of covering up for a trickster

Although my case is extreme in a way, the white lies you have been told really do seem small by comparrison.

Relax dude... Go to see her in October! Book the flights, send her a copy of your itinerary and stuff. Let her know your serious and watch how things change
