Im very sorry for your loss. It’s always hard to find out someone lost their life even when you haven’t been in touch for a while. Don’t feel like you’re not entitled to your feelings, even if you hadn’t been in contact, that person was part of your life at some point so don’t feel bad or guilty for being sad.
Just hope that his family is able to find the strength and healing from his passing, especially with such a tragic loss. Hope you feel better ❤️
