i will never understand that stupid craze about expensive engagement rings... i engaged to my wife without a ring. It was just a very emotional situation, i was sure that i wanted to ask her... and then i just asked. No ring, no special event planned out or something... just asked her, and she said yes.
People paying cars worth of money for a ring is so unbelievable for me.
Look into turning off desktop effects while playing there is a key combo for that with f12 of I remember correctly.
