When Friends Share About Relationships That Don't Align with Our Beliefs

I have a lot of non-Muslim friends, and naturally, they date. Whenever they talk to me about their relationships, I worry I might unintentionally make haram actions seem okay. I can't really lecture them on Islamic rules since they don’t follow them, so I try to steer clear of those conversations. If someone tells me they're seeing someone new, I’ll usually say something like "Masha’Allah, that’s exciting for you!" to keep it light. If they have a crush, I might joke about it playfully. If they ask for advice, I focus on making sure they’re treated well and are okay-because, as a friend, I care about their well-being. But when it comes to tips on flirting or approaching someone, I always act like I have no idea or just say I can't help with that. It’s all about balancing friendship and faith without overstepping.
