Yeah, I can imagine. I've seen a lot of people on the website saying that they were more attached to their engagement ring than their wedding ring and for me it's the opposite.
I wear my wedding ring continually but because of running/gardening - i'll take off my engagement ring and it'll sometimes stay off for days.
I'm very attached to both, but then jewellery has always been the one material thing that can get sentimental for me. Cars don't, other stuff doesn't but jewellery is personal and signifies time, people and places.
Darren designed my engagement ring himself so it actually is unique in every way, my wedding ring was bough in a shop but we had to look long and hard before we found one that would compliment the engagement ring.
D has a wedding ring too, his choice and as he was married for 9 years before he met me he wanted something different, and it is different.
