Well, after reading through it all, I'm gonna have to take back my post.
I thought the girl came first and the car came next, but it's the other way around.
And she knew about your finances before and such when you guys met. So she knew what was going on...something doesn't sit right
Dude, you're 26!!! The world is your playground right now! I know that the pain and hurt are at it's peak when it just happens, but believe me, time heals everything. I'm not saying it will take an hour, but it will get better. You've done what you could to get in contact with her to no avail. Like other's have said, give her a cool-off period. Try contacting her after some time has passed, but not too much time. Offer to talk (
talk) with her about everything that needs to be resolved,
not about the argument you guys had.
Even if things don't work out completely, at least you'll get closure and then you'll know that you MUST move on!! As soon as you know you can move on, get out there and be a beast at meeting women!!!
