Is my ex dying?

My ex was in the same store as me a few days ago we didn’t have a terrible break up but we don’t really talk anymore. We caught up on life and he told me he’s having a health battle with his heart. And we talked about that for a few and we told each other have a good evening and walked away

Today he texted me and said “well.. pray for me and hug your daughter for me”
