gf gave me a small engagement ring

Showed the ring to my friends and they were all pretty shocked at how cheap it was. She makes decent money so its not like she couldn't afford something nice. I'm wondering if I should end the relationship because it seems like she doesn't value it AT ALL.

Wait, your a guy who cares about how much the ring costs? dump your gf for a bf. girls give a shit about how much rings cost, not guys.
