Death of a loved one—?

Is it true that when the person you love dies you die thereafter? Like how true love is for a husband and wife your other half. What happens if you never meet ur true luv & u die? Do they die too?

Some but I've known a few couples where that has happened even seen it in a movie

My husband was murdered in 2010. And yes a part of me is lost forever. I will never look at the world the way I once did. We were in our early 20s and just bought our first home. Things were beautiful. And then they were a fucking nightmare. But eventually I did love again.
