Can someone from another faith share in Iftar and Eid celebrations?

Salaam, I really hope it's okay because I've been blessed with so much amazing Afghan and Pakistani food this past month while visiting my Muslim friends for Iftar. I just want to make sure I'm not causing them to do anything against our deen by joining them. As a Christian, I have many close Muslim friends, and I genuinely value being part of their traditions and celebrations, even though we have different beliefs.
