No longer with ExP. We were engaged a couple of years ago, but I have him my ring back when we split.
We did get back together for a while last year/this year but I've decided it's over. I. His efforts to get me back, he's proposed (left my original ring in an Easter egg which I took to work). I've said no. I still have the ring.
I feel like it's my ring, it is beautiful. My friends all say they would give it back as it's 'his ring' 
Genuinely don't know if iABU to keep the ring!
