I wear mine because it was what was exchanged on our wedding day – it is symbollic of the vows we made to one another. However these are just my thoughts and I don’t judge other married men / women on whether they have them or not.
Also its almost a rite of passage = guys don’t do jewellery but a wedding ring is allowed, makes you feel all grown up innit.
I have a plain ti ring so wear it most of the time, although when doing diy think i should remove it as yanking on a crowbar can hurt my finger when theres metal on metal rubbing against flesh.
Call me sentimental but at times it can be a ‘crutch’ – when things are tight and I’m on my own, it reminds me theres hope and love just round the corner
