Dating a Guy who keeps picture of dead GF?

Claire

So I’m dating this guy who apparently keeps a picture of his dead gf from 17 years ago. I’m not sure if this is a cultural thing ( he’s Mexican) but I find it a little awkward. I respect his past and the dead but is this an issue?

He also wears a necklace that she gave him before she passed away. So every time we’re intimate all i see is the dead ex gf’s necklace dangling from his chest.
