Should an actor's real-life relationship affect what happens on screen?

One thing I've always found fascinating about movies is how much of the story happens before the cameras even start rolling. We see two actors share a convincing romantic scene and assume it's just another day at work. But behind the scenes, there can be conversations about comfort levels, boundaries, and how far an actor is willing to go for a role. It raises an interesting question: should an actor's real-life relationship influence what they're willing to do on screen? On one hand, acting is a profession. Audiences expect performers to fully commit to the story they're helping tell. On the other hand, actors are still people with partners, families, and personal boundaries that don't disappear the moment filming begins. What's interesting is that some of the most believable on-screen romances came from actors who had no romantic connection off-screen at all. Meanwhile, some real-life couples have shared the screen and generated surprisingly little chemistry. The more I learn about filmmaking, the more I appreciate how much trust and communication go into these scenes. What looks effortless on screen often involves careful planning, discussions with directors, and agreement from everyone involved. For me, it makes the final performance even more impressive because audiences only see the finished result, not the work that went into making it feel natural. Do you think actors should separate their personal lives completely from their professional roles, or is it reasonable for real-life relationships to influence what they're comfortable doing on screen?
