Yes I have -several times when I was one of the only female reps on the road up North in Western Australia.
It was my standard excuse for someone NOT to join me while I was eating dinner -I would say something like -I am expecting my husband shortly, or things like that as I did not want to always sit with someone at night after a hot, difficult day.
Of course there were the times when I did not say that!!
I've never pretended to be in a relationship. I was almost tempted to play along when one of my friends wanted to do it with me. But then I wasn't prepared to lie. I was thinking that the pretence may come back to haunt me, so I didn't go through with it.
Many separated/divorced women wear their 'Wedding Ring Jewellery'!
Many still married, women wear no 'Wedding Ring Jewellery'.
It's individual reasons', & in the former, to deflect unwanted attention, is a very good reason to continue wearing jewellery.
If a woman has been married, & especially having had children, then separates &/or divorces, aren't her rings' 'worth' the 'hard work' done, & so, not feel 'guilty' if she wishes to wear them?
Along-time friend had her husband just decide to go off to the other side of the world, thinking 'the grass was greener'. They'd been married, at this time, about 23 years' with two children, now grown up. After he decided to return, 6 months' later, & continue the marriage, the wife had all the gold of her rings melted, diamonds removed, & a BRAND new ring made composed of the diamonds set into the gold as an acknowledgement of their 'new start'. They're still together after 20 years'. Well done in a tricky situation!
So wedding rings' jewellery can have an 'interesting' life!
